Had the 3GS, had come from 3 touchscreen phones before it. Nokia 7710 being the first back in 2005! I liked the idea of apps but was against the iphone as I knew some of its limitations before hand but then I played with one and was blown away how smooth it was!
I lost a lot of functionality that older phones could do but for the experience and apps it was worth it. I jailbroke it, realised what I could really do with it then it was a natural progression on to android.
