It's not anything more than a rumor right now, but reports are floating around claiming that "select developers" are already receiving prerelease versions of the upcoming iPhone SDK
. The kit is said to already be producing native apps, and development is being compared to other sandboxed APIs like Google's OpenSocial -- apps have "clear limits" on what they can do, and interactions with the OS are mediated, presumably to avoid any security or performance issues. That jives with what Steve-O said
about managing access, but again -- this is all just a steamy cloud of vaporous nothing till that first app shows up in iTunes.
