A beta release of the iPhone v2.2 software began seeding to developers yesterday. While much of the developer community is still digging to try to figure out what exactly changed in this release, the iPhone-dev team has already torn it apart. At least in its current state, v2.2 is vulnerable to the same jailbreaking methods already freeing handsets around the world.

They do note that the recently released 2nd generation iPod Touch remains unjailbroken, and mention that they’re toying with the idea of hardware based hacks in order to smash through that challenge.

Besides a UI change in Safari which moves the Google search bar out into the main interface, has anybody gotten wind of any changes yet?
