Iphone is an "Apple" product. They are first in many ... and Iphone stand as "an elegant and exclusive machine with an artistic mind". This is what I wish to call Iphone. If you use then you'll come to know.

Blackberry in short (BB) is more of a business like phone, where the features and glamour is quite less. Many carry BB just for a show-off inspite of the fact that they never make use of the exlusive BB services. BB tend more to business ppl and so called pretenders...where as IP is more of with an "entertainer" aspect attached to that.

Hence, it's quite natural that IP becomes more popular.......
