Ah.. time to go down memory lane. I was such a phone swapping whore, it wasn't funny, at least until the iPhones.
Started with Nokia dumbphones:
1999-2000 - Nokia 3210 -> 7110 -> 8210 -> 8850
2001 - tried out Sony Ericsson t68i
2002-2004 - back to Nokia 7210 -> 7250 -> 7250i -> 6630 & 8910 -> 8910i
2005-2006 - Enter the smarterphone: Sony Ericsson P900 -> P910i -> P910a
2006-2007 - experimented with windows mobile (ugh) : Cingular 8525 -> Samsung BlackJack II (SGH-i617)
2007 - Apple iPhone
2008 - Apple iPhone 3G (tried Blackberry Bold 9000 - left to rot in drawer)
2009 - Apple iPhone 3GS (tried Blackberry Bold 9700 - finally figured out not a blackberry fan at all)
2010 - Apple iPhone 4
After all that... it's the iPhone family that has kept me the happiest!
Started with some Motorola brick when I was 11, of which I cannot remember its name,
then a Nokia 3210,
Sagem MY-V55 (seriously bad phone)
Sagem MY-V76 (even worse)
Samsung E900 (best non smartphone i've had)
then my lovely iPhone 3G
and now my fab iPhone 4
2004- - Some cruddy Nokia phone. The one almost everyone has owned.
2006 - Virgin Mobile Vox
2006 - Motorola Razr
2007 - iPhone
2008 - iPhone 3G
2009 - iPhone 3G S
2010 - iPhone 4
3 Sony Ericsson K800i (they all had firmware issues but I liked the phone so much I kept getting it replaced) then a Sony Ericsson C902, then my 3GS. Before the SEs i was using crappy Motorolas and Nokias
