Download APP WORLD from your browser on your Blackberry, then download the apps from there. Or, go to www.blackberry.com or www.crackberry.com or www.mobihand.com on your laptop and email specific apps to your email address on your phone. Then click on that link with your phone through the email and it will download it to your phone.
Blackberry's need to have their batteries pulled often so they run smooth. Download quickpull and have it set up to simulate a battery pull every night when you're asleep. It won't be successful if you have it in a magnetic case so be sure it's out at night.
G Tach i think its called. I found it in app world, it uses the accelerometer built in the phone to estimate HP, G force, 1/4 mile times etc. Just turn it on and put it in your pocket or on the dash, and boom, pocket dyno. 14bucks. Not sure how accurate it is but maybe one of you guys that know your HP can try it and see how it does.
my bro has one and he is a manager of a radio shack so he sells tons of them.he told me about vlingo and app world and i have gotten a few ring tones from crackberry.com it's a cool phone but the trackball is pissing me off to the highest point of pisstivity. it's about to take a flying leap into the lake if it don't get right
