Mostly for the Blackberry Messenger and Twitter. I check Facebook while I'm on the go. I really hope they will come up with much better version soon. I really like the iPhone version of Facebook.
I tend to be on facebook a lot as well as texting, internet and other random apps including twitter. Peopleofwalmart.com is fun to go on when you have nothing better to do too.
