I have been playing fair with my iphone 3gs, I paid for all my apps, over $300 worth, and I didn't jailbreak, ( not that I have a problem with it ) but the minute I start seeing ads pop up on my phone, I "will" jailbreak my phone, because someone with find a way to disable the ads. Nothing p me off more then forced advertising. it's in ours faces everywhere we look. It wont be long until HARRP start transmitting commercials wirelessly into our brains. and NO, I am not kidding, this can be done already.
