Hi, we made available a XDA/O2 GSM P3kit, which measures GSM/GPRS radio strength in real time.
pls try it out, http://www.mobilegx.com/ppc/p3kit/p3kit.html
It is tested on O2 PPC2000 edition, possibly works on XDAII, T-mobile as well.

Hi Tech-Guru's,
I'm having O2 XDAII ROM 1.60.00WWE, Radio 1.08.00. Can I use EDGE (Enhanced Data rates for Global Evolution) with this device? If not, any ROM updates?
Thanks.
M.Muhelen
if you mean edge as in what some people also call 2.5G then no like 3g (UTMS) it would require new hardware inside the xda2
wait for xda3 if you want support for new cellphone systems
EGDE is "2.75G" as I know... GPRS is "2.5G".....
The download speed of EGDE is almost as fast as 3G Network, but based on GSM technoology.
XDA2 doesn't support EGDE now.. and seems not planned to support in future.....

About as correct an explanation as it gets, spot on mate, yes. EDGE, in effect, would be 2.75G...
GPRS is 2.5G(eneration)
Edge is Enhanced Data Rates for Global Evolution, a kind of development of standard GPRS capable of running almost as fast as current 3G.
But for it to work, the phone must support it hardware wise, and the network too must support it.
I am a Los Angeles resident an am noticing UMTS starting to appear in the area, and in particular in the Foothills area of LA. I have a HTC TyTN rinning on the Cingular network which is SuperCID and which is running the South African HTC ROM which includes Radio ver 1.18.00.10.
When UMTS is picked up by my phone the reported strength of the signal drops dramatically. I may go from 4 bars on the GSM network to 1 or no bars with the "U" showing. I have DK Today loaded and under UMTS it often reports single digit % fpr signal strength.
Has anyone else experienced the same? Could this be just teething problems as Cingular rolls out UMTS in LA, or could this be showing up a problem within HTC's South African Radio ROM interfacing with Cingular?
Any thoughts would be appreciated.
Your GSM is using 850MHz band with stronger propagation characteristics while your UMTS network is on 1900 MHz. In LA thery will be island of UMTS for a while
That makes sense that UMTS will be "islands of presence" for a while, but does it make sense that when I am in a UMTS area the signal strength is virtually zero?
Could there be anything in the Cingular Radio ROM that might tuen into the signal better if I changed to that radio ROM?
Thanks
try it and let us know if you notice a difference.. make a back up of your current stuff so its easy to switch back.. but IMHO the 1.16 radio in the current cingular rom sucks, i had serious issues with it here in st. louis.. but 1.20 radio seemed to clear up some major issues, i still have some minor issues, but im patient and know that will be fixed in due time!

Its normal, mine does the same thing and i have the 8525. My guess is the phones priority is to pickup 3g if available. If the signal is there, it will pick it up whether or not the signal is as strong as the edge signal. If theres no 3g, then it'll pickup edge. If your not close to the 3g tower, then the signal will be very faint. If you're 1 to no bars with the the 3g signal, then you'll most likely switch to the edge signal with full bars because your probably closer to an edge tower than you are to a 3g tower! Someone please correct me if im wrong!!!!
Update
Thanks for the input. As posted elsewhere, I was having difficulty upgrading the Radio ROM. Today I was successful in upgrading to 1.20.31.10, however, I shall be away from my place of work where the UMTS signal is most prevelent until after Christmas. I can report back later next week. In the meantime 1.20 at least initially seems not much different to 1.18, but time will tell on that also.
I've also invested in an external aerial for the car. Unfortunately the connector is very tight so might not be as pratical as I had hoped, but we'll see on that score also.
One final point. I have the "ShowUMTS" cab loaded, although perhaps it was not necessary on my TyTN. My understanding is that UMTS is only broadcast on the 850 & 1900 bands, whereas GSM could be strongest on any one of 850, 900, 1800 & 1900. That seems to only allow 2 of the 4 choices under the band selection, being "Auto" or "GSM(1900+800)+UMTS(1900+850)". I'll keep it on "Auto" firstly, and then will switch to the other selection after. If any one has suggestions for what else to try it would be terrific to read them.
Happy Christmas all.
the 1.20 radio didnt solve any signal issues for me(but im always in decent coverage anyway), however it did solve some weird feedback issues... with 1.16 from cingular i would have choppy calls on GSM and on 3G i would have this really weird digital feedback, was the weirdest thing i ever heard.. 1.20 got rid of those problems for me...

Wrong!!!
Selection is based on network preferences. Your network provider can do almost everthing within its network range with your avaliable service. Right now that is true - if you have 3G coverage it will select it, then GSM. But for example - if company is testing 3G network in Someplace and it is not ready for customers even thou 3G signal is avaliable your handset will not log to that network.
Hope this clarify. It's always network not phone.
With all these radios with increasing version numbers ( presumably updates) and comments about not working on some networks which can be a problem for international travellers.
I have a few questions.
- Do these radios all work well on the 2G (GSM, GPRS Edge networks)
- Is the problem of compatibility only on the 3G networks ?
- Do other manufacturer 3G world phones work well in all countries or is this specific to the Hermes platform radios?

Typically when I travel I'll try to find a radio which works well in the country I'm visiting, but this can be time consuming. I've so far found that by forcing my phone to GSM only I will often get better phone reception, but obviously at the expense of data - so you may be right that the main problem is with the 3G side of things.
I've found that the best rom so far is 1.38.00.10. I've used it in North/South America, Europe, Asia and Asia Pacific and don't recall any specific problems. 1.50.00.00 also seems promising but I always travel with a copy of 1.38 just in case.
My phone is the Vodafone VPA Compact III using with a UK O2 contract SIM. I also travel with an unmodified Nokia N80 on my Vodafone SIM. Often the Nokia will have a signal when my Hermes won't. This is usually because the Nokia has logged onto a different network and when I force the Hermes to that network (from auto) everything is fine again.
Hi, i am newbie yet, but by what i read, RADIO is responsible by the communication, with GPRS, with 3g too for exemple.
My HTC TPT7272 works on dual-band trough the HSPA/WCDMA, only on 900 and 2100 MHz...
But here on my region, my provider provides the access for 3G only on 850/1900 MHz, so, i have to use EDGE to connect to the internet, but my HTC support 3G...
Does anybody know, if I can upgrade my radio, or if is possible to change the work band for 3G by the radio for provide my access to the 3G?
Grateful
Henrique

I hope that would be the case, but I have yet to see it work for the many months on this forum. There are strong evidence that this is a hardware limitation on the Raphael. Unless you have a FUZE (AT&T version of Raphael), you are out of luck for 850/1900 HSUPA until someone comes forth with the software for us to try.
but so, u see some possibility?
if anybody knows, please contact me, i would love to use my HSUPA, crap of provider, could provide full signal..
if some version of raphael works on this band, could i install his radio? i really wants to navigate on 3G signal...
LOOK IT:
Fuze/AT&T(HTC RAPHAEL 101)
Cellular;Phone
Cellular-Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900, UMTS2100
Cellular+Data+Links: CSD, GPRS, EDGE, UMTS, HSDPA
FUZE WORKS ON IT, on 850, anybody know if I install his radio will work??
The official specs on HTC's website doesn't inlude 850/1900 as part of the HSPA (3G) connection, only for EDGE.
I have tried many of the radios here and none gives me 3G connection for my carrier, which is on 850 band for HSDPA.
I have tried 1.02.25.19
and then 1.02.25.28
and then 1.02.25.32
and then 1.08.25.20M1
and now 1.11.25.01
but I haven't tried any radios for the other phones since my TP is not security/CID unlock. You can try all the raphael radios, then consider getting CID unlock to try the other radios if you wish.
I have been on this forum for a few months and yet to read anyone successful in getting a TP working on 850. If you do succeed, please share this knowledge for I am sure there are still ppl out there wanting the same thing as you do as well. Myself being one of them.
I wish you success in this endeavor.
man, i am iniciant, i took my HTC TP in around 1 mounth, and one point that almost conviced me not to buy this pda was the 3g band.. i wait this more than you, lets wait if anyvody with much experience can post one help for us

follow these threads and you will have your answer.

they haven't updated recently, which means there is no more 'news' on it.
you can try searching for 3G in the elite RC3 thread up in the sticky section.
they still don't have a solution either.
you can keep waiting.
the best radio for good gsm reception? please help?
There's no real answer because signal reception depends on your used ROM, your Provider and your country! So the best way to let it know is to test all Radios by yourself!
Also, the type/age of ROM will have minimum or maximum radio restrictions.
it depends on model and country.
Radio from niki200 works very badly on my niki100.
Also radio from my niki100 works very badly on niki200
The official HTC Radio 1.65.28.25 is working great in many countries
