I'm heading over to TMO store to have them test da battery for me (I never knew that Battery has 90 day warranty, I thou' it was 1 year as a whole device) but I was lucky since it's within 90 days! If TMO says it is the battery, then I have to call TMO to have them mail me new battery, if TMO says it's the device, TMO will replace it.
On the same note...do you guys know how much the battery cost for 8700g?
TIA!
