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. This makes the use of WiFi even more attractive than it already was since the user does not need additional applications in order to enjoy the benefits and savings of WiFi.
There is a fee associated with UMA through cell providers such as T-Mobile, Rogers and AT&T who usually require you to pay fees starting at $10/per month for Hotspot service. However, keep in mind that calls originating as UMA are billed for their duration as such and at no additional expense, even if you leave a WiFi area and the phone switches back to GSM. This, combined with unlimited domestic WiFi calls, and the $10/per month fee is a bargain for heavy users.
Ergonomically the Curve offers the spaciousness of older Blackberries, with a 35-key Qwerty keypad with a white backlight and keys that are well designed for easy, fast typing. The 8320 Curve is available in both Titanium (gun metal gray) and Pale Gold (champagne).
