We can certainly try to help out with whatever is up with your S2
There are a few variants here for the S2, and I assume you probably have the International version?
See here for the different models:
Android Phones - Android Forums
And you can start a thread over in your device forum so others with your device can help.
If you are not sure of what you have, and if you are able, go to menu/settings/about phone and that will give us more info about it
Edit: ah, I see you have found your forum!! NICE!!
