    Re: Wifi????????????????

    WiFi - if you have a carrier with UMA (i.e., T-Mobile) and your phone supports UMA (i.e., 8320), then you'll be able to make phone calls wherever you have WiFi access, even if you can't get a normal GPRS signal from your carrier. For a lot of people, this means that they'll be able to make calls from within their home, anywhere on campus, in an office, and at a lot of retail places (e.g., starbucks, panera, etc) that provide WiFI.

    With T-Mobile, if you initiate the call via WiFi, that call is part of your flat-rate "hotspot @ home" service, and doesn't go against your minutes allocation. You can initiate the call within the wifi area, walk outside and have the phone seamlessly transfer the call to the GPRS network, and it's STILL, essentially, free (at least part of your flat rate add-on, which is currently going for $9.95 a month).

    With WiFi, your data downloads will be extremely fast. Web browsing will be extremely fast. Your call quality will be excellent within a UMA/WiFi area.

    If none of that matters in your case, then WiFi isn't important. But with increasing access to free WiFi in more and more areas, there's a good chance that this will be a bargain for many people.

    UMA is a next-generation fixed-mobile convergence technology standard which allows for seamless handover between cellular networks and fixed IP networks (hot spots). Handsets with UMA technology allow free voice and data communication both in mobile and fixed modes. UMA is Unlicensed Mobile Access. Hope that answers your question.

    UMA is "unlicensed mobile access"... essentially a system that supports seamless roaming and hand-off between local area networks and wide area networks (e.g., a local WiFi network and T-Mobile GSM/GPRS network).

    Here's a link from Wikipedia with a good article:
    http://en.wikipedia.org/wiki/Generic_Access_Network

    Here's an overview from UMAToday:

    ...and here's another good article that describes it well:
