It has many different applications you can get. Right now I have MSN, AIM, and Yahoo messenger, I also have the facebook application which is pretty neat. There are lots of applications that you can get. My mom has the Iphone and the Iphone is larger than my blackberry, the other blackberry is more bulky but the curve isn't too bulky. I actually have att and I have never had any problems but I guess it might just be the area. When I want to check my myspace I just log onto the internet and go to myspace mobile and it loads very quick. There will probably be an application coming out soon.
Hope this helps
