HELLO EVERY ONE:


just bought my iphone 3G at att store,like 3 weeks ago.



I have tried everything: 3g off,push e mail off\,wifi off,brightness half way...but nothing....my battery dies in about 10 to 12 hours.

can i ask the att guy to replace my iphone for a new one,since i'm on warranty..or they will send me to an apple store to replace with a refurbished one?

any advice would be appreciated

thank you in advance
