I need a new phone and have never had a touch screen phone or a smartphone before.

I want an android phone because there is a way to change the qwerty keyboard for a traditional T9 keyboard, which I find a lot easier and quicker.

The question is which one is a good phone to get. I don't necessarily want the latest one, in fact would prefer cheaper rather than newer. The only thing I want to do is instagram so it should have a decent camera.

Opinions please, although please don't tell me to get an iphone. I don't want one.
