Blackberry my friend is mostly used for emails and stuff there are no games or anything in there if you like a business type of a mobile with a querty keyboard and a small screen with maybe 3.2 megapixels camera then go for the blackberry its nice 

The iphone mostly is used for multimedia and gaming personally i consider it an 8 year old's toy :P even the most serious applications in this mobile are like games haha :P anyways it depends upon your need the blackberry has an internet service you can chat with friends has many useful applications that iphone dosent have also iphone has many applications that blackberry dosent have 

I don't like i phone

if you like touch and qwerty keyboard both then you go for the blackberry 9800 or the latest 9900
