No US availability has been announced for the Samsung Galaxy S III, but should you have the proper amount of dollars to import a Galaxy S III on May 29, you’ll be able to use Samsung’s new flagship over AT&T’s HSPA+ network just fine. We’ve increasingly been seeing unlocked European handsets coming with the 850 and/or 1900MHz bands, which is what is required to use a phone over AT&T’s 3G network here in the States. Some online retailers like Negri Electronics are even showing the Galaxy S III as having the 1700MHz band, which would allow the phone to also work on T-Mobile (making it pentaband, like the Galaxy Nexus).
If you’re eager (read: impatient) to get a Galaxy S III and want to buy one outright from a European retailer, it can be preordered over at Clove for £429, or around $700. Or, you can wait a few more months and get a lesser-priced subsidized unit when it hits all major carriers.
