You can now Buy Officially unlocked iPhone 4 for $649 in USA

Although most Americans won’t benefit from this too much — Apple has now started selling unlocked iPhone 4′s in their US online stores but they will still only work on AT&T’s 3G network. The big attraction is, of course, being able to take the phone along when you are travelling abroad and simply replace the MicroSIMs where ever you go. Most people from other nations are already very accustomed to this swapping of sims when travelling to another country. Although the prices for the(16GB a $649) and  (32GB $749) may seem quite high for American buyers, they’re quite a bit more affordable than the unlocked pricing elsewhere. If you decide on the Black iPhone 4 you can have yours delivered within 3 business days , or three to five business days if you purchase the onlocked white iPhone 4.
