Apple has just released version 1.1.4 of iPhone firmware. There does not seem to be any obvious new features with this new firmware compared to version 1.1.3 but the tools for unlocking the iPhone will not work yet.
The update is available from iTunes (162.1 MB) as usual. If you have an iPhone desim unlocked or Jailbroken - we advise waiting some days to get the first reports from other users.
