hey I just got a T3 love it and getting use to it too. one problem I read about and kinda notic right away is the battery life which is very bad. and some more research shows that it is a 3.7v 950mAH which is very week used in older cell phones with did not do much. in any case I am planing to get a treo 600's battery and do a switch and I pick that for two reasons. 1. since it is an internal battery that wasn't ment to be a quick replace so it has a pin plug set up like the T3 and second its a 3.7v 1600mAH a more powerful battery. my problem or question is ....is there anywhere I could get battery size spec and has anyone tried some other steps in battery conversion. if I could get my hands on battery sizes for both batteries I'll go ahead and experinment for compactabiliy issues if any.
