I would say microSD card but another thing i could not do without is the screen protector. I hate it when it when there are scratches that i cant remove on my blackberry
I would be lost without my "Lieutenant Uhura" bluetooth earpiece. In fact, I am considering having part of my upper ear reshaped to better suit the fine features of the earpiece because after all, it's all about the Curve, isn't it?
My 8130 has 1gb card, a black skin for better grip, and a 665 Plantronics that I use while I'm driving. I haven't put any music in it yet: I'm still trying to understand how to do it.
BB8830WE Amzer desktop cradles, extra batteries, invisibleSHIELD, rubberized spring clip swivel holster and my favoite of all is the black case and black keypad
