Ok I tried this Advanced Configuration Tools and it was fine at first, but now it has messed up my phone.

No matter how long i set the time to disconnect the data call, it disconnects it as soon as it goes idle, it disconnects. This means that when surfing, it disconnects and has to reconnect between pages, even if it has only been 2 seconds.

I seem to have it fixed for skyfire (not sure how but it started working) but i am still having trouble with opera mini (Esmertec Jbed Java). Anyone have similar problems or know a fix? I have gone through my connections and settings, removed the app, reinstalled, change settings, soft-reset 3939342 times... same problem.
