I don't think Cingular needs to worry about the Wi-Fi usage for data needs. But I am guessing that they will be concerned about use of Skype or VoIP applications over Wi-Fi. Which will I reduce the regular voice traffice, which is not desirable.
Maybe it's one of the first phones that will support UMA (which sounds like GSM via unlicensed spectrum, like WiFi).
Quote:
By deploying UMA technology, service providers can enable subscribers to roam and handover between cellular networks and public and private unlicensed wireless networks using dual-mode mobile handsets. With UMA, subscribers receive a consistent user experience for their mobile voice and data services as they transition between networks.
Although I don't see HTC listed as a participating company, Cingular and T-Mobile (specifically US -- yay!) are both listed.
