I bought this phone in replacement of my lost v400, I was really excited about this new model I got, however, not everything's perfect, I'd like to share with my thought with whoever will buy this phone, but again, the choice is yours :)(...)the good1. good battery2. SUPERB DISPLAY, there are 3 themes came with the phone, nice and pretty3. you can take videos4. good reception, headset and speakerphone works great(...)the bad1. camera quality is SURPRISINGLY low, my old v400 took better picture than v551 :(, for example, when you switch your phone to night view in the dark, it will start picking up any brightness(such as street lamp) and that one single light source will WASH OUT the entire picture completely, very disappointed2. I wish they have better design for the look of the phone(outside)3. polyphonic ringtone is great, but you can't hear it too well even if you turn it to loud mode(unless you set your ring to be "siren" or "continental", those are pretty loud)4. the video file you took will be in '3gp' format, which I have no idea what kind of software can play it if I transfer it onto my pc, I guess it can only be view on the phone(...)I hope these comments help!*answer to the question from below, you move your cursor to the time you want to edit, below the screen you'll see "disable" click on that to disable/enable the alarm clock, if you want to edit it, simply click on the stript bar(the bottom with 3 horizontal line) and choose "edit", you should be able to edit your time...good luck, if any more question, feel free to e-mail me
