I have an iPhone 4, also had the 3g and original iPhone. My power button stopped working so it's a pain to lock the screen, and I can't take screenshots anymore. I also want a larger screen 3.5" doesn't cut it anymore. I know the next iPhone will likely be larger but who knows when it will be released. I imagine July at the earliest. I really like the look of the Nokia Lumia 900 which is due out in March. I'm a big apple fan owned tons of macs throughout the years and currently own iPad 2, apple tv and macbook pro 13". Should I make the jump to windows phone or wait for who knows how long for the iPhone 5?
