My phone is dying in 6 hours now ever since I put a T-Mobile SIM card in there... I used to be able to get 24 hours moderate usage with WI-Fi on constantly, 36 hours light usage... now it dies in 6 hours on 3G??

I have bluetooth/gps/wi-fi scanning/all that crap turned off, 3/4 of the desktops disabled, only one active widget (calendar), TOR polling SMS at 2min intervals (same as I had before on wi-fi), nokia messaging for one account, and smartreflex enabled. And it dies in 6 hours.

I just bought the phone like one month ago so I don't think the battery is dead... something is ******ed between the SIM card and the phone though.
