true, I wasn't sure if Apple cared. but the firmware should always be hackable. back when i was into hacking psp's and stuff, everyone thought that 2.6 was unhackable. but then we found out how and now people can downgrade even newer firmware. thanks though. hopefully when i get mine in may i can either get one that is already hacked and i know i can do new stuff to it, or the newer firmware will be hacked by then
I think the community has been established. It will always be a "throw down the gauntlet" sort of thing to the hackers of the world, and they'll probably always step up. So I predict hacked iPhones for as long as the product exists, even if third-party apps mitigate the popularity of doing it.
I think that will depend upon how much Apple charges for the software they will release through iTunes and also how selective they are on what they allow to be sold. I love the software that is available now and will gladly pay for most of it but the small utilities and fun programs may no longer be available without hacking. Time will tell.
I ran out and bought a phone 2 days before the release of 1.1.2 firmware cause I thought it would be months before they found a jailbreak. They jailbroke within hours. I think you'll be fine. As long as code is writeable by man there will be men to hack it.
