Man am I glad I didn't wait for a white one! iPhone 4 is soon to be obsolete, and it's STILL not here!
Sorry man! The iPhone 4's display (and Ghz CPU) is going to make it much more relevant than say, a 3Gs...its got tons of life left in it. Now, the iPhone 5 probably WILL have the dual core A5 (just like the iPad2)...and maybe more storage capacity. But thats no big deal...IMO, its the "retina" display thats the game changer.
