I've successfully written and simulated a couple of applications, and paid my $99 fee. I want to upload my programs to my iPhone3G to try them out, but I am scared to go further because part of the user agreement says my iPhone will be locked into development mode forever and can't be used as a regular device. Does that mean I have to sacrifice my iPhone and a 2 year contract just to try it out? Does that mean I can't use my device normally (as a phone or data device?) (Sorry I posted this question in the wrong forum, so I have put it here too).
