I've had the phone for 14 months. It's been very reliable. I've dropped it many times, got some chips and scratches on the cover, and the phone keeps performing at top grade. The battery life is getting shorter over the time tho. I start to charge it every day, when I used to charge it every two days.Voice quality is superb. Menu is easy to follow (I never needed to read the manual.) What I like most over other phones is that it captures absolutely beautiful pictures with nice colors and reasonable details. I also purchased a data cable to tranfer pictures onto my laptop, easy!Unfortunately, the signal reception is poor at my place. Before you buy this phone, check the reception of T-mobile in your area. This is a great phone if you are lucky to live at a 5-bar region. Otherwise, get ready to apologize (to the other side of the line) over and over again every time your call gets dropped. :PBy the way, I'm not sure if this is sth. about T-mobile or the phone-- summer daylight saving time doesn't get adjusted automatically, you have to restart the phone (twice a year).
