Hey, I am mostly using Blackberry Bold 9700 now, as the email, messaging and IM are really fast and the phone is good too. But I also have 3GS, which I use also, time to time. Browsing, you know, and stuff. Do you think I should go for iPhone 4? I really hate to have two devices now. Do you think iPhone 4 will make any difference for me? Will it make more communications/messaging functions better? Or should I just forget it and stick with 9700?
