Recently, HTC officially published new software for the Touch Diamond, which upgraded it from tri-band to a quad-band GSM phone. This is a nice improvement for the U.S. owners, who will now get better coverage for phone calls, but unfortunately, still will not be able to take advantage of the faster 3G data. However, FCC just revealed that another hardware variant of the Diamond will feature 850/1900 MHz UMTS/HSDPA, which will be suitable for usage in AT&T’s network. When this version will be available on the market is still unknown, but HTC has previously noted that it should happen during the second half of the year.
Another new FCC approval reveals a variant of the TyTN II (also known as the Tilt by AT&T). It has the absolute same specifications and design as the original one, but changes the UMTS frequencies and now supports 1700 MHz. This means it will be usable with T-Mobile’s 3G network, which works on this frequency. However, there is no information whether and when it will hit the market.
