As summer approaches, I decided to put my new 9780 back to its box and use my 9630 for three months. I'll be keeping the Bold for quite a long time and since summer is a period that most phones are dropped, I don't wanna risk it.
What I wanna ask has to do with BBM contacts. I have them on my Bold and I wanna transfer them to my 9630 and, when fall comes, I wanna transfer them BACK to my 9780. How do I do that?
