Hey guys, i'm still new to this whole BlackBerry thing, so i'm looking for some help. I just purchased a BlackBerry Curve 8900, and i'm having trouble with my BlackBerry messenger. I'v been trying to add one of my friends, but she tells me that she didn't receive an invitation. She's also tried to add me but i don't receive anything from her. I'd like to know how to fix this problem. If anyone can help me i'd really appreciate it.
P.S: we both have the same device only her version of the BlackBerry messenger is newer than mine.
