Apple has just released iTunes 8.2. In this release, Genius bar now does video. It also supports the soon to be released 3.0 firmware.
It might seem compelling to upgrade. However, if you have a jailbroken iPhone, you might want to postpone the upgrade. The iPhone Dev-Team has warned that this release breaks QuickPwn and PwnageTool. The iPhone Dev-Team has also stated that they are not going to release a new versions of jailbreaking tools until the 3.0 firmware is official.
