Not trying to cause problems for developers but as a consumer, should we stop buying apps because of OS 3.0 coming out in two months? Will developers offer free upgrades or will we be buying all of our apps again? I think this is particularly key in apps that will use push notifications. I'm hoping that apps like beejive will not make their customers buy "the next version" when 3.0 becomes available. Again, not trying to cause problems but I don't want to spend all of my iTunes giftcards now and be stuck after upgrading to 3.0.
