I started with a Philips C12, then moved to a flipper, but I can't remember what that was now. I then had one of the original Sony (pre-Ericsson) phones, a J something or other, which had lovely polyphonic ringtones.
Next came a run of Nokias, 6310i, 6230, and an N82. I then had a few SEs, the K750i, K800i, K810i, before moving onto BlackBerry, of which I had the Storm 1 (which famously met with a wall!) and Storm 2, which then led to the iPhone 3GS, and, currently, the 4S. I may have missed one or two along the way.
