I currently hav an iPhone 3GS & I'm hoping to get an iPhone 4. Mainly because it's the first phone that has apple's retina display, which then went on to other devices like the new iPad & the MacBook pro. It's also the first phone that has the metal band around the stricture that is used as the antenna. Plus it's design is also very much improved from the 3GS, which glass on the front & the back. Who do you guys think? Should I get it?
