Just wanted to say hi as I'm a new board member and iPhone 4 owner. I was owning a Palm Pre previously and so far, I have no regret. Of course each phones have their plus and minus, but all I can say is that my iPhone 4 fulfilling my need as far as feature goes on a smartphone.
Welcome, I am also a new Iphone user, came from the BB Bold 9000, and loving the Iphone 4. I did jailbreak to increase the functionality of the phone for my own purposes, but still love the level of polish that this exquisite piece of hardware has! No regrets here!
