im not 100% sure which one you're getting, because there are 2 versions. I used to have the first version.
pro- similar screen to the iphone, very sensitive etc, solid neat finish...
con - The 1st version of the phone: the whole screen is one giant button so it is very frustrating to type up sms' quickly, believe me it is very annoying. Unlike the iphone when you put your finger on a letter on the blackberry, the letter is highlighted and when you want to enter that letter into the text you have to push down and that makes sending messages slower and painful.
No wifi connectivity
That being said i heard that in the second version they removed the giant button and it seems to be alot better and also it has wifi so im sure that would be handy, but i recommend that if you havent already, that you go into a shop and ask for a working demo model to try it out and see if u like it before u buy it.
if u dont like it then i'd go for the iphone, if ur not an iphone person, go for the N-97, if thats too expensive, other brands are getting better
good luck mate!
