Review: BlackBerry Pearl Flip
Apps
The BlackBerry OS uses Java, so you can find, download and install a host of Java-based applications for the Flip. The T-Zones site is a place to start. The Flip also comes with Docs To Go, Maps, and other business-oriented applications pre-installed.
Bluetooth
The Flip's Bluetooth radio supports a large number of profiles. I was able to pair it easily with other phones and my Mac. Passing files back and forth was easy. Pairing with headsets - both standard and stereo - was a snap. Sound quality suffered a bit, though.
Clock
The external display of the Flip is an awesome clock. The entire thing is a huge clock that is easily read when inside. It can be set to analog or digital. It is a bit harder to read when out in the sun, but either way, one quick press of a button on the side of the phone, and you'll be able to tell the time in no time.
