MyBlackBerry Open to Public
My BlackBerry is another social networking site build for BlackBerry related stuff. In fact it was supposed to be open long time ago but finally RIM has opened the registration for public.
My BlackBerry the "official community for all things BlackBerry" and it features a number of social network type features: you receive a profile which you can customize to your liking; you can add friends and send private messages; you can learn about top apps and browse accessory reviews. The root of it all is multiple discussion forums for applications, accessories, devices and tips and tricks.
