Cell phones - Good service?

[PollyannaFlower46]

My contract with Sprint is running out, and I've been generally very happy until recently when my under warranty phone broke and they began giving me a hard time about repair and replacement. I've been without a cell for over a week and allegedly my new one is on the way....their lack of customer service just may be enough for me to sign up elsewhere....does anyone have a good carrier that they reccomend?
