What cell phone service and phoen would you recommend?

My Sprint 2 year contract is up. I am looking for possibly a new service, and a new phone. I don't use alot of minutes, and I really only used the phone as a phone, and to text message. Although some of the cool functionality of the iPhone would be cool.

Does anyone have recommendations?

What service is the best? What phones are the best?

at&t's service is amazing. I have never had a problem getting a signal anywhere. it's definatly worth looking into. I'm actually looking into getting a samsung propel myself, it looks really cool.

If anyone could help me out:
