Apple has just released a new firmware update, version 3.1.2 for the existing iPhone and iPod Touch range, which contains no new features but fixes an important issue with cellular network reception. The new software fixes dropped cell connections until the iPhone is restarted, according to Apple.

However, it looks like the update does contain a new baseband version in order to fix the issue, therefore if you have an unlocked iPhone 3G or iPhone 3GS, do not update until there is confirmation from a trusted source, like the iPhone DevTeam. If you’re planning to jailbreak, you should wait as this firmware version is currently incompatible with the latest jailbreak tools. But updates will soon be released to resolve the compatibility problem, according to the iPhone DevTeam.

The complete-ish list of changes, according to Apple’s cryptic update notes, is as documented below:

  • Resolves sporadic issue that may cause iPhone to not wake from sleep.
  • Resolves intermittent issue that may interrupt cellular network services until restart.
  • Fixes bug that could cause occasional crash during video streaming.

Clearly, it indicates no new features, unless there are some hidden ones. ;)
