Since I am dropping my sprint service I want to disable the 4g and 3g radios but leave the wifi enabled. The best way I have found so far is to put it into airplane mode and then enable wifi. Is there a better or more permanent method to do this?

LTE On/Off from the Android Market provides a shortcut to the radio list; there's a "turn off radio" button at the bottom.
It was intended for use on the Thunderbolt, but works great on any device.
Keep in mind that this does not persist through restart.
Thanks for the info.
I dont have my view yet but I read this on the hero forum
"In the dialer put in *#*#4636#*#* then go into Phone Information then scroll down and select turn off radio."
But instead of the dialer you enter it in the calculator (from what I hear from viperboy). He tested it and it does disable the radio(not sure if just wimax or 3g as well) and I'm not sure if it sticks after a reboot or not or if it leaves Wifi turned on (something I find annoying about airplane mode, having to enable wifi every time I boot)
FYI: if you enter the passcode as !+!+4636+!+! in the calculator, you can indeed turn off the radio. Unfortunately, it comes back on after you reboot. The better option, then, is to keep it in airplane mode and enable the wifi when you need it.
I use the lte program with a shortcut, bt dont work in airplane mode btw.

I have a Vibrant with no data plan (I'm in Wi-Fi 99+% of the time). How can I turn off both the 2G and 3G radios, both to save battery and to make sure I'm not accidentally charged for using data?
I searched around and there are a ton of apps and widgets to toggle between 2G and 3G or disable 3G (Smoda, APNDroid, etc.), but I haven't found a way to turn both radios off. I also poked around in Service Mode, and the only options I found were to toggle between 2G/3G, not turn the radios off. Any ideas?
Not sure you can. Airplane mode will kill the WiFi too. But the best bet would be to stay on 2G and disable data roaming.

Trigger Airplane mode, slide down notification area, turn wifi back on. Bingo. I do this at School in areas where I get no reception at all but has wifi access.

Another option would be *#*# info#*#* then go phone information ..scroll down and hit "turn off radio" and your good to go. Or you can hit menu and press "disable data"

APNdroid shuts them off Ive used when i used my vibrant as prepaid to save battery. After you disable you have to reboot
Thanks for the help, everyone! Airplane mode + wifi is perfect.
(About APNDroid: as far as I could tell, it just changes your APN entries to invalid addresses; it doesn't actually turn off the radio. So you can't use 3G, but I was afraid it would still use the radio while searching for the invalid networks. But I don't have a great understanding of HSPDA, so I could certainly be wrong on that.)
just a heads up, airplane mode also disables calling/texting
Yes the radio would still be searching for networks if you disable the apn
If you get the Juice Defender app, it has a "Toggle Mobile Data" widget. It's a nice 1x1 widget that turns off the mobile data radios (but not Wifi). This is the best solution I've found.

Hi,
I have terrible 3G (UMTS) reception at my office, but good 2G (GSM), so to save battery and make the phone as usable as possible I switch to 2G when at work. I used to go to Settings -> Wireless & Networks -> Mobile Networks and switch on "Use only 2G networks", and lately I've been using the "Toggle 2G/3G" function in the CM7 notification power widget.
However, it is slightly annoying to have to remember this toggle every time I enter/leave the office, so I'd really like to have an app that does this for me. Does anyone know of an app that can toggle 2G/3G based on either location or time? I'm using CyanogenMod 7.0.3 if that makes a difference.
I've tried a few different profile/setting switching apps, but none of them seem to be able to do this (while all can turn APN on/off, which I don't want. I want data enabled all the time, just over GSM part of the time). Even the apps that claim to have a toggle for 2G/3G seem to be just shortcuts to "Mobile Networks" settings.
Would really appreciate any helpful suggestions
You might consider buying Tasker. It can do what you wish even on a geolocation basis. So whenever you enter/leavr certain location proximity it will do whatever you set it to do.
Thanks, tasker does just what I wanted.
So I have a data-plan on my phone, and that's it. The actual 'phone plan' is all VoIP, so the only time I need the phone's 3G radio on is when I'm not connected to a wifi network.
I've found many programs that can automatically do an action when I connect/disconnect from wifi, but for some reason I cannot find an app that just disables the phone radio. Airplane mode is not desirable because it disables all connections. I've found programs that attempt to modify which radios are disabled in airplane mode, but it seems like none of them are capable of leaving the bluetooth radio on. I always need wifi + bluetooth on, but the best I can do is airplane mode with wifi, and that's it.
Now I know it's possible to manually disable the phone radio and nothing else under phone info. Does anyone know of any applications that will press the 'turn off radio' button for me? Preferably, I would want two; one that turns off the radio, and one that turns it on so that I can coordinate the actions in my automating program.
Also, in case anyone is planning on saying 'herp derp you can reenable wifi and bluetooth manually after going into airplane mode', NO that is not what I want.

You could try this app: http://www.appbrain.com/app/airplane-mode-modifier/com.wparam.airsettings and you could also check out this script: http://forum.xda-developers.com/showthread.php?t=1217038.
NB.: You cannot enable bluetooth while in airplane mode.
The first application I already tried, and although it works for wifi, it doesn't work for bluetooth for some unknown reason.
That second script is interesting; I can turn off the mobile radio, but I can't turn it back on. The guy that wrote that post seems like kind of a tool for acting like he just wrote a script, when really his entire script consists of only:
Code:
#!/system/bin/sh
#!/system/bin/radiooptions
radiooptions 1
I checked the radiooptions API, and radiooptions 5 is supposed to turn the radio back on... but it doesn't seem to work.
Hopefully somebody knows a way around this :/.
I have a evo view 4g and its not in service. Ide like to save battery by completely disabling the 3g/4g support. Is there a cwm package or something in the system I could remove to disable the radio?
If you just un-check mobile data it turns the 3g/4g radio off..

I run my View in airplane mode and then just manually turn the WiFi on and off.
No it still searches for signal thats what the bars are on the status bar. So in essence its still using power to search for a cell signal to connect to. Doing that stops data connection but it doesnt turn the radio off. You can do that on a phone but going through dial info thing. On our tablet you cant just do that it has no dialer.

It helps if you use the Quote function so we know to whom you are replying.
Look, in airplane mode my View does not search for signals. Airplane mode has to stop the radio, that is what it is for. I'll take a look at my View tonight, but I don't think I have any bars on my status bar, since I keep it in airplane mode all the time.
EDIT: If the radio is indeed still on, HTC has a serious problem in integrating hardware and Android.
Ok, I'm on my view now and there is no signal strength icon. Turn on airplane mode to shut down the modem.

If I go into developer settings and switch off Mobile data always active (in an attempt to save a little power when the phone is on Wifi), I find the phone often doesn't enable data when I leave Wifi. I have to cycle airplane mode to make it do it.
Anyone else finding the same bug? Or even using this setting?
I've had dropped connection issues since day 1, with airplane mode being the only way to restore my connection. And this was with Mobile Data always active set to on.
Who is your Carrier??
Have you noticed similar issues even with mobile data always active?
When I go to building with no cellular and come back outside. The phone doesn't automatically reconnect to cellular, leaving me with no service. What a strange bug.

EE in the UK. Works fine almost all the time so far if I keep mobile data active.
Vodafone Romania, toggled the setting off in dev options as soon as I got the phone. Data switching works fine still.
Try going into the testing menu (dialer code *#*#4636#*#*), select phone information, select 3dot menu on top right corner, try switching around between Europe and automatic. I'm my case ,selecting Europe presented various weird connection issues , biggest of which was that the phone refused to connect to LTE unless I used "automatic".
