The 770I, as with other unlocked phones, is available from several sources. Try PhoneSourceUSA, a Hong Kong company with offices in Nevada. The company ships extremely fast and offers some of the best high-end mobile phones I've purchased from overseas. (They sell direct and on eBay.)
Another good source for all EuroAsia phones is GSMArena.com and, on eBay, Integron Technologiies.
U.S. phone buyers should know that if you purchase a Nokia, Sony Ericsson or other phone intended for use in another part of the world, there is NO warranty service in the U.S. Nokia is rapidly expanding retail stores in the U.S.--and other manufacturers may do the same--but, until then, Tri-Band and Quad-band mobile phones, usually with an "i" after the main model number--lack warranties.
Tri-band phones operate at 1900Mhz, the predominant U.S. frequency used by AT&T, T-Mobile and a few smaller cellular carriers. There are few areas of the country only offering 850Mhz analog coverage, because carriers, through their roaming agreements with other carriers, blanket the country.
Generally speaking, if you stick to to major brand names and buy from a reputable source, you'll have few problems with unlocked GSM phones. (Nokia and Sony Ericsson are the easiest to configure for WAP, SMS, MMS and email over the Web.) T-Mobile also has an unsupported phone division with an automated setting service.
All major U.S. carriers--AT&T, Verizon and Sprint--now offer 3G services on selected handsets, and T-Mobile will introduce its 3G service in 2008. 4G is the hot technology currently under development overseas, offering download speeds of over 100Mbps.
