Samsung Flight SGH-A797 (gray, AT&T)

Pros: The keyboard is nice

Cons: Two items:
1. The phone power cycles automatically when sending text messages. Does it about 50% of the time.
2. The sound quality on the phone is not very good

Summary: I've have AT&T (who have been helpful so far) replace the phone with a refurbished model now for the 3rd time. I'll need some other solution from them moving forward. It's obvious to me that this phone has a flaw and giving me a refurbished one that someone else turned in for the same problem (most likely) doesn't really solve the problem.
