Hi guys...First off thanks to the entire dev team for their brilliant work. and others here for their
suggestions
Now my issue is battery drain....i know its been discussed a lot ...but plz bear with me.

I got a brand new 3GS (Obviously FW3.0) from apple..for full price lol... to use with tmobile usa.
I got the iBEC and iBSS files as advised (Using windows pc XP home).
Then i JB with redsnow and used cydia only (No icy as advised).
There were no issues except for the battery drain.

I tried many things to minimize the drain like location off; push off;auto brightness; low brightness
& inspite of these, my iphone wont last a day. sometimes at the end of the day its dead...as in fully drain.
I mean i talk like for abt 2 hrs a day, check email 3-4 times; and do some online browsing (like devteam updates, comments etc).....
So, i tried full restore again from itunes (you know...shift and restore 3GS ipsw file), Re-JB and unlock....but...battery life dint improve a bit....

Could any kind souls help me with whats going on with my brand new 3GS???
Worst case... i'll restore again & go the apple store to exchange/return,

Any input very much appreciated...Thanks
