Don't go to twister. They sold me an 8gig iPhone after telling me it was a 16 gig when I specifically asked. Tried to return it less than a day later, and refused to take it back.
Wireless solutions may have one an if not they have them unlocked, recommend wireless solutions, I don't trust twister wireless
I've dealt with Twister Wireless several times and never had a problem. If they dont have a Cricket specific phone they will most likely have an unlocked phone that will work on the Cricket network. Twister does unlocking, they sell cases and screen protectors for about every phone known to man. I've had them repair a couple screens and they've jail broken a couple iPhones and I've never had a problem.
