DigiTimes reported HTC will be making the first Windows Mobile-based UMA handset for T-Mobile. We saw the Nokia phones, Blackberry 8120, 8320 and Samsung phone at T-Mobile which offers WiFi@Home. In a technical terms, the WiFi@Home is called UMA (unlicensed mobile access). In other words, you can use enable the WiFi connection on the phone and it will search the open access point. If the connection is strong and stable, the phone will automatically log on to the WiFi network. Any call made via the WiFi network, it will be the VOIP calls. Keep in mind that the WiFi@Home service is not free unless you sign up for the $9.99/month WiFi@Home plan.
You can check on more detail on the internet and will find out the UMA standard is getting more and more popular.
