I recently got a BlackBerry (8900) and have been perusing this site before my purchase. I am also a member on BlackBerryForums, but I think I like the "feel" of this site better, so I decided to sign up.
This is my first BlackBerry but I'm already in love with it! I'm not a "business" type of person (not now, anyway), so I guess I'm a BB "consumer" user. At least I'm over 21 (LOL...)?
This forum is great! I've already gotten out of tough spots regarding my BB with the help of this forum.
Check out the BlackBerry 101 How-To Lecture Series ! This will help you with the basics such as downloading apps, themes, wallpaper, ringtones. It's also a good idea to browse the forums and read as much as possible. Many questions you have are answered there already!
