Which is the best t-mobile camera phone?

I had this phone from past 3 years and all other friends are using Nokia phones and phones are older than my phone but still Nokia phones works faster and better than this phone. The signal of this phone are irritating and if you will place it in once spot than you can notice that its bar move up and down all the time. The camera is very good and I was amazed at the quality of the picture and the phone design is good. I like phones that I can hold and dial with one hand but in this phone buttons are very irritating and so small that you will not at all fell comfortable while typing anything on this phone. Sometimes when I flipped it open and the screen went blank and came back a few seconds later, but it took almost a minute to initialize the address book. The all I can say about this phone is that it has cheap quality for a relatively cheap phone. So I will advise you not to buy this phone and go for any latest Nokia model.
