Conclusion: The BlackBerry Curve 8320 is an exciting device. We've seen a lot of "me too" devices that are copies of last year's successful model or are simply clones of the same phone offered on another carrier. But the Curve's UMA and T-Mobile's excellent Hotspot@Home service sets the 8320 apart from the 8300 and most other phones on the market.
Excerpt: The Blackberry 8320 Curve is the latest iteration of the once AT&T exclusive 8300, but with at least one major improvement. The 8320 uses a wonderful new technology called UMA or Unlicensed Mobile Access, which allows the user to make WiFi calls seamlessly and without the need for a separate VoIP account.
Excerpt: First came the trim, consumer-friendly BlackBerry Curve 8300 . Then came the Wi-Fi-enabled BlackBerry 8820 . Now there's the BlackBerry Curve 8320, an impressive PDA phone that combines the best of the previous two models and has an added bonus: While the 8820 supports Wi-Fi for data only, the 8320 lets you make voice calls over wireless 802.11b/g networks too.
