I just bought one and I don't know how to charge it! I can use it, but only when it's plugged in the wall! When I unplug it all my data is gone and it won't turn on..

It says just to plug it in with the wall outlett cord..is it really that easy? Will it say when it's done charging and how do I know if it IS charging?? I'm clueless.

*BTW-I got it at a gargae sale..brand new. *

Thanks!
I really want to try this thing..so please answer this as soon as possible!
