So many special things we can find in Blackberry and not in many other phones:
* If you are sending/receiving anything with bluetooth you CAN NOT do anything else or even leave the screen.
* Smaller screen sizes compared to other mobiles
* if your phone is switched off, you can NOT connect to any WLAN without having a sim card inside your phone
*very less entertainment apps available for the Blackberry
* RIM (Research In Motion) - the Blackberry company- made a HUGE NET loss last year, their CEO resigned just recently!
so yeah, Blackberry is the PERFECT phone :) i love it so much!!!!
