I'll be really disappointed if you don't release a new iPhone this summer like they have every previous year. I'm not sure if the quake and tsunami in Japan played any part if the delay though, but I would certainly like a refresh sooner than later, and all of this speculation is just frustrating. how to convert m4v to wmv I think this guy is kind of out of line blaming ipads for the un-employment rate in the US, times change, before we were making cars with our bare hands now about 95% of a car is made by machine. And also that whole bit about china is a little ridiculous too, as americans id say probably about 80 to 90 % of our household products are made in a foreign country including the vehicles we drive.. I feel that this country is in bad shape because of suit wearing millionaires that blame iPads for job loss and un-employment&#65533;&#65533; hahaha&#65533;&#65533; Makes me laugh.
