so i love my phone, its been great, but let me explain the whole situation.
it is a unlocked, from the store, galexy s2. i have it registered with AT&t, and it is about one to two months old. i have had no problems with it untull about 4 days ago. it started being wierd, below 50% battery it would think it was being plugged into a charger when it wasnt. then the next thing i knew, the battery was dead, and when i pluged it in, it just kept restarting over and over. now it completely wont turn on. im worried about this because it is unlocked, and im not sure how the warrenty works.

p.s. it just showed the startup animation, and then died again. nothing for about 5 min sence then.
