Hi all, I am new to BB, just bought used 9360, first I was amazed, then got some problems, like I said I am new to this so need any help I can get. Thank You in advance.
The 1st thing that happened was that when i got my used bb 9360 the battery was very low and i charged it for 5 minutes or less and it was fully loaded?? and after 8-9 hours (the battery icon was showing that is was full), the phone just went off and i couldnt turn it on...after 10 minutes of getting the battery in and out of my phone(LED coverage indicator flashed the red light when i was putting the battery in the phone without charging), and putting it on charge (4-5 times) the phone started to charge.... so should I just buy a new battery or what?

the second thing, which I really cant figure out, is: can I use facebook, whatsapp, viber, emails, with data plan, not BB data plan?

ok, this is it for now, I am sure that I will have many many more questions. Thanks
