sgs2

I've got an offer of exchanging my SGS2 with my Dad's iPhone 4S. yea, I suggested him to buy that. Apparently he's finding it tough to use and he asked me whether he could have my SGS2. I spend most of my time using Linux. Sadly, iOS Phones don't support my OS. I'm aware about the lack of USB...

Guys I accidentally broke the screen for SGS2. Any idea how much will the replacement screen cost? Can I use the one year warranty for this?
