A couple of weeks ago, I told you about Wi-Fi Sync, a jailbreak app that allows you to sync your iPhone over wifi. At the time, Wi-Fi sync was only available on Mac OS X.
An update is now available for Wi-Fi Sync that brings support for Windows users, and also for the iPad.
You can get Wi-Fi Sync from Cydia for $9.99. You will also need to install the free software on your computer.
