BlackBerry Storm with Verizon. It was cool at first, now it is just annoying. Touchscreen typing is not for me.
Poynt is a good app for information on restaurants or businesses, gas prices, theater information and movie times. It also works with Google Maps to get directions to those places.
I think Google Maps is a lot better overall rather than BlackBerry Maps. With the latest upgrade, it now shows contact information for businesses and restaurants on the maps.
Quickpull to battery pull my phone early in the morning so my phone is not slow as shit when I wake up.
Weatherbug for weather. The icon shows the current temperature, high/low and a sun or a rain cloud depending on the weather.
