Android os/services still use data even with droidwall enabled

I rooted my phone yesterday using MyGKernel and installed droidwall.I allowed all apps to use wifi and disallowed all of them from using 3G but android background services still use data.I got background data and autosync disabled.Also I noticed that after rooting my phone,the screen turns on by itself in random times.I'm running Android 2.3.6,please help !
go to settings - wireless and networks/mobile networks/ use packet data, data roaming. both off, to disable data via cell provider.
i dont know about the screen issue, some app waking you unit up?, you dont need droidwall if you disable packet data.

But I need the packet data to be on for a vodafone app called vodafone buzz.Its an app that lets me connect to fb/twitter/msn/yahoo/gtalk for 1 dollar a month and I don't get charged for internet data.But the problem is the android services use data for no reason even with droidwall enabled.Oh and I fixed the screen thing,it was a problem with an app.

[Q] Wifi Data Usage

is there a way to see which app uses most data rather than the accumulated wifi bandwidth usage? i think i saw this option before, or i am just wrong.
Try watchdog 3G
afaik, apps should be listed in data usage in settings, however it doesn't is there anyway to reset it?

Show WiFi Usage Data as Network Provider Usage Data

Hello to all,
I am looking for a trick through which i can show my WiFi usage data as Mobile Used data. It can be very helpful for retrieving data from third party apps like "Gigato". So that whenever I am outside my WiFi network, I can access the data which i get free through WiFi. Looking forward if any one has any suggestions. Thanks in advance.

Wifi settings?

Can anyone explain to me what 'restricting wifi networks' actually does? I cannot seem to notice any difference between when a wifi network is restricted v not restricted! Also, Wifi power saving mode? Does it really preserve battery if its constantly analysing your phone?
If you use Wi-Fi, you can also set your device to restrict data usage on Wi-Fi networks that are mobile hotspots or mobile data. This will help you optimize your data usage by preventing apps from using background data or large downloads on these networks, only download use when Wi-Fi available..

Question Notifications on mobile data and wifi

I've noticed I'm not getting all notifications when I'm using mobile data. I have to open the app to check if there are any.
As soon as I turn on wifi they all come in. I've checked several settings, but can't find why this is happening.
These apps have no battery restrictions. And restrict data usage for these apps is set to WLAN and mobile.
Am I missing something?
