Apple is now selling unlocked GSM iPhone 4s to U.S. customers, here’s why (from the product description):
>If you don’t want a multiyear service contract or if you prefer to use a local carrier when traveling abroad, the unlocked iPhone 4 is the best choice. It arrives without a micro-SIM card, so you’ll need an active micro-SIM card from any supported GSM carrier worldwide.
Nice move, coupling this with the iMessage launch — man I bet U.S. carriers are pissed that Android isn’t as ‘hot’ as iOS.
