The Bold specs I have seen stated "Network Support - UMTS: 2100 / 1900 / 850MHz, GSM: 1900 / 1800 / 900 / 850 MHz, GPRS, EDGE and HSDPA 1.8 Mbit/s & HSDPA 3.6 Mbit/s networks"

"Normal" Third-Generation (3G) Frequency Range:
Base transmit (BTx) 2110 - 2170 MHz
Mobile transmit (MTx) 1920 - 1980 MHz
BTx / MTx In TDD (Time Division Duplex) 1900 - 1920 MHz

However, I thought in the US, 1710xxx8211;1755 MHz and 2110xxx8211;2155 MHz will be used instead; as the 1900 MHz band was already utilized. (As also stated above)

So, all, should I say most, non US-specific 3G devices will not function properly within the US? And all US devices will mainly only work in the US?

So, the business users will have to switch devices when travelling???? :crazy:

(I understand this is not a RIM issue - a frequency problem)
