I have an iPhone for a portable palmtop computing thingey. The cellphone function if deliberately turned off. I had four different cellphones in the last four years. All of them started misbehaving two months into usage, I used to always forget them at places, or forget to take the phone with me, or to charge it. None of them were any good for making or taking calls, gave me a headache, and all of them eventually ended up in pieces after being thrown into a wall. 1) AIM: "Check your mail." 2) Gmail: "Turn on your phone." 3) On the phone: "Get online, will ya? I need you now." 4) Phone goes into wall. With a fair amount of force. Don't have a phone anymore, and not planning on having one ever. That tech don't work out for me.
