This is without a doubt the best phone I have ever had. T-mobile just keeps getting better and better. I have never had a dropped call and reception is great unlike my friends with Verizon. The phone is easy to use, great sound quality, beautiful display and looks and feels top notch. I tried the Motorola Rizr Z3, it doesn't even come close to the quality and performance of the Samsung SGH-T739. Thrilled with this phone.

This phone is wonderful and has all the best features. It works well without any crashes. My only concern is for the speaker quality which could have been still louder and clear.

I am SO happy with my new Katalyst. I switched from Cingular to T-mobile with LetsTalk (best move ever) and could not be more pleased. The phone works perfectly, I get way better reception than with Cingular, the speakerphone works pretty well (I only wish it was a little louder for when I'm talking in the car), texting is really easy, and it is JUST what I was looking for, aesthetically. This is a great phone.

The Samsung SGH-T739 may look good, but it is not a cell phone you want to get. The bluetooth only works for headsets which is a problem. Speaker volume is below average. Also, it has it's own USB cord which cant be used with other Samsung phones. Overall, I would give it a 6.5/10. It is not good but, not the worst.
