This variant of the Curve adds Wi-Fi with UMA, but is otherwise similar to the original 8300 model. Other features of this consumer-oriented BlackBerry include a 2 megapixel camera, music player, stereo Bluetooth, 3.5mm headphone jack, and memory card slot.

The Curve offers solid performance, a great design, excellent messaging features, and the addition of Wi-Fi is icing on the cake.

Wi-Fi:
Attracted to lower service costs? The world of Wi-Fi awaits you. With your BlackBerry® Curve™ 8320 smartphone and a plan¹ that includes Wi-Fi, you can:

• Access BlackBerry data services over virtually any Wi-Fi network and save
• Get great service, even where mobile coverage is typically weak or unavailable
• Use your smartphone as both your home and mobile phone — with full voice functionality² (if your service provider offers UMA/GAN support)
• Seamlessly move between Wi-Fi and mobile networks — your calls, email and browsing data transfer between networks to maximize coverage and minimize cost

Blackberry Maps:

• Whether you're going to your client's office or the latest downtown hot spot, BlackBerry® Maps makes it easy. Check maps for fast turn-by-turn directions virtually anywhere. Simply click on an address in your address book, type it or paste one in and you're practically there.
  
• You can make BlackBerry Maps even better with a Bluetooth®-enabled GPS receiver for the BlackBerry® Curve™ 8300 or BlackBerry® Curve™ 8320. The BlackBerry® Curve™ 8310 comes with built-in GPS to make it even easier for you, your coworkers and your family to share your locations with each other.
