Well it's been 2 years to this day that I upgraded my 1 year old 3GS (my 1st iPhone) to an iPhone 4. I have never been so happy with a phone before, I practically live on this device. Online banking/emails/Dropbox/Twitter/Calendars/GPS/LogMein Remote Control/Movie tickets...It's completely changed how I do things. I used to use my Desktop PC for everything but all I do is play the occasional game on it now. I've never had a single issue with the iPhone, love the form factor and everything about it. I'm incredibly excited for the iPhone "5" that is hopefully launching next month. Quite frankly I'll be sad to sell my iPhone 4, it's been so good that I don't even want to part with it!
