Hours after the white iPhone went on sale internationally and a lengthy downtime, it is now available through the U.S. Apple Store, as well as AT&T and Verizon's websites. As mentioned earlier, the handset should be available at Apple's brick-and-mortar stores when they open later today. Apple's front and iPhone pages has yet to be updated with the now-available status of the phone, but will most likely mirror the "finally" ads that are appearing on AT&T and Verizon's sites.
For those who have been waiting, happy shopping!
