I have the iphone and love it. It has its quirks but which phone doesnt? IF u r planning to get one, I will wait for a month for the rumoured 3G version. Why 'rumoured'? Its all a rumor till Steve holds it in his hands at the show. :)

If you want a super stable iphone, dunt load the 3rd party apps on it but then again, i have crapful of apps and its very stable.
