[Galaxy S II Q&A, Help & Troubleshooting] ginloin:
Hi there. Long time listener, first time (Android) poster here (and previously infrequent Windows Mobile poster).

I'm in Australia and ordered a Galaxy S2 from the UK, which I love. But the last couple of days I've noticed MASSIVE unintended 3G data use. I only have a 1GB limit and I was going along merrily for the last week. Then yesterday all of a sudden in one day I'd used around 300MB. So I did some tweaking, installed 3G Watchdog and this morning I'd used another 400MB!! The reason I installed 3G Watchdog is because it can tell me my data usage by app, and it turns out (according to 3GW) that the offender is AP Mobile, which had received 339.1MB this morning! So I'm just wondering if I could get some help with this.

AP Mobile as I understand it is purely an RSS type widget. Doesn't seem to be an app anywhere for it, and when you go into the widget, there are only like 2 configurable settings. Can't even choose which feeds it gets, from what I could tell. I had looked at it initially and set the refresh to 3 hours, but later removed the widget. It must have kept updating though (but even so,for a mobile device seems like a massive amount of data still!). I didn't realise this, but have now set the refresh to 'none'. I hope this works! Does anyone know much about it?

OK, so my questions really are:

1. Does anyone know how I can make sure this never accesses data again? I use Juice Defender but it doesn't even appear in the list of configurable apps (though things like the BBC iPlayer do). Perhaps because it's only a widget? Is there another app that might help me do this?

2. Ages ago I used Android Assistant to kill the APM process on startup since I wasn't using it. But it must still auto start itself at times (perhaps this was connected to the update interval, which is now set to 'none'). Is there an app that could persistently disable this (and other) service(s) without rooting?

3. Which leads to my third question. I'm assuming the only way to uninstall this (since it came as part of the original ROM) is to root my GS2? I saw the thread on rooting a GS2 but I'm not sure about all the terms, like which specific firmware I have and which kernal to install after rooting. I'm more than happy to root it but had a bit of trouble working out what it all meant. If I was to root it, is it simple to uninstall original firmware apps or is the only way to install a custom ROM?

EDIT: Ok, I think I have a handle on rooting my device now, my apologies for not researching thoroughly enough. I think I know which firmware, kernel etc. I have so it's just a matter of doing it now. And then I can use Titanium backup to uninstall stock Samsung apps? Is this the best/only way to do this?

4. I'm generally happy with the device as is so I don't necessarily (yet) want to install custom ROMs. If I only root it, without installing a new ROM, will I still be able to install Kies updates as and when they appear? And does that unroot it?

Sorry for all the questions! And I'm so sorry too since I know most of this is completely n00b stuff to you all. This is my first Android phone so still learning the ropes. And if I should have posted elsewhere please reprimand me accordingly. I did search before posting, but being a new platform, I don't have a framework yet for knowing the right search terms exactly.
