I am new to this whole blackberry thing. I just got my first and am trying to set it up. The guy at the phone store was kindof a ****** (ADHD, I think) so I didn't feel comfortable asking him too many questions. Does anyone know exactly how long I need to charge my phone each time to get the best battery life? It seems to say it's fully charged after about 20 minutes! My last couple of phones indicated that the initial charge should be 8-10 hours and to run them completely out every time before recharging so the battery doesn't get a memory of "short" charges. Any suggestions for this phone?
