Careful - for me the iPhone served as a gateway to Apple land. ;)
I bought my 3G - which was already becoming obsolete - in 2009. I still use it to play MP3 and take pics, but that's it. When we moved here, I got a little LG phone (mainly so that we'd have some kind of bill here in Vegas and could start building a credit story and all).
I hate that piece of junk with all my heart and I do miss my iPhone, but since the only time I use the phone is when my wife calls to tell me she's on her way back from work, there'd be no point in spending more $ on an iPhone.
