It’s also still got an eye on its wi-fi business: in the press release talking up the 3G network, T-Mobile has promised it won’t get distracted by all this mobile telephony and will keep on adding new hotspots to its wi-fi network across the US.

Its approach to 3G data is a bit of an odd one: the operator said “T-Mobile expects its high-speed data network will be available in those cities where a majority of its subscribers currently use data services”. Surely, turning on 3G is just what’s needed to get more people using data? Holding off from turning on high-speed services doesn’t exactly seem to be the best way to get more T-Mobile customers ready to pay for mobile email and the like.
