Newbie here kinda threadjacking this, well, thread: I have a 8310 Curve which I connected to my Mac (10.6, DM 1.0.3 build 19) and was going to let it upgrade the OS (currently at 126.96.36.199 and going to 188.8.131.52? Is that a good move?). Now this blackberry is rather empty -- I got it to learn how to program them and, right now, to compare with my ancient iphone -- so I told it not to backup any data since I have none. Also, I am going to use it with t-mobile, who said if I wanted to use it all I would have to do was to let them know so they would change my data plan from the iphone (yeah they are smart and do not care as long as they are getting paid) to the BB. Would that mean I need to wait for that to happen before trying to backup/update the OS/somehow copy my address book/whatever to the phone?
