First, iCrakced (YC alum) and iFixit are profitable for a reason... Its nice to hear you took care of your device - but its clear it is an overly fragile design.
Also, no it isn't that I REALLY like the iPhone - I have had other devices - but I have chosen to have a policy of NOT paying for my phone.
My work pays for my phone and plan. I don't have a choice on the phone in some cases. (some companies refuse android devices due to perceived security risks, RIM is dead..)
16? Really? Then you must really, REALLY love the iPhone. At what point does one say 'enough is enough' and switch to some other phone?
