Looks like we have new iPhone firmware as well this morning! In addition to refreshing their MacBook and MacBook Pro lines to Penryn processors, Apple has also released the new iPhone 1.1.4 firmware. Go ahead and check for a new update after connecting your iPhone to iTunes. Of course, if you are
unlocked, you may want to wait for a bit while everything gets figured out. Apple is saying this release is all about bug fixes - but we are hoping there is also some iPhone SDK magic in there somewhere.
EDIT: Okay, if you are jailbroken, go ahead and update. ZiPhone still works, and will jailbreak the just-released 1.1.4 firmware update…although the developer recommends waiting until he can fully test. Your call.
