As I said yesterday, the Samsung SGH-T709 appeared to change since we saw it at CES. Instead of promising integrated Wi-Fi, the T709 is now listed as having "high-speed wireless connectivity." It turns out, though, that Wi-Fi capability is there but just by a different name. Using UMA (unlicensed mobile access), the T-Mobile-bound T709 switches between cellular networks and Wi-Fi hot spots with few interruptions in data. UMA automatically detects the fastest and most cost-effective network.
