In the past, I've used 3G in the US mostly for Internet connectivity for my notebook with prepaid SIMs, as only my Europe / World – 3G USB dongle could tune to the frequencies used in the US. But now with the new Nokia Symbian^3 phones with pentaband UMTS support such as the N8 and C7, that 3.5G indicator also popped up on my mobile phone when I recently switched it on in Los Angeles, both with the T-Mobile and the AT&T network. On first impression, Internet connectivity on the phone feels reasonably faster than just over EDGE. A definite advantage in an international meeting where dozens of international Blackberries hang on to the two GSM networks. Very nice, I love pentaband UMTS chips!
