i have a 8120 from at&t, and its probably 5 months old. my battery dies between 3-4 times a day (this started 3 days ago).. i went to at&t(yesterday) to exchange my battery and i thought it was going to resolve this situation.. i wake up today and my phone is dead !!! (again) ..my battery is still dying when i havent even talked on it... im not getting any of my emails either, (??) im not sure if this is related
