Same capacity as factory. I'm not sure how likely it is for RIM to have an extended capacity version... The only one they have done is for Nextel and that's becasue Nextel wanted it to match the performance of other BB handhelds... the Direct Connect is a battery hog.
Isn't the 7100 battery the same as that is used in a few Nokia phones? What are the specs on those batteries (and do they have extended life versions) vs. the 7100t's in Mah?
