No one knows exactly if firmware 1.1.4 paves the way for SDK but it is now available. The update is all of 162.1MB, so besides the bug fixes Apple must have something bigger in store.
For legitimate AT&T iPhones and iPhones subscribed to their exclusive providers in Europe, there has been no reported problems so far. GFor unlocked iPhones, there has no report of upgrade problems. Jailbroken iPhones still work with the upgrade, and it has been reported that ZiBri jailbreak works as well. So has Apple finally given up on jailbreakers. Are unlocked iPhones coming next?
The update is also available for the iPod Touch.
