The beta for Wi-Fi Sync 2.0 was just released last night, by developer Greg Hughes!  Wi-Fi Sync lets you sync your iPhone over a WiFi connection that way you don’t have to use your USB cable to connect to iTunes!

There have been a lot of people waiting for this to release for quite a while now, and just last night Greg Hughes posted the link on Twitter. Now, today if you’re on the mailing list, you should be getting an invitation to try it out! Unfortunately, the first version that was released last night crashed nearly immediately, but lucky for us, build 70 was released this morning and the crashing issue is fixed!

As of now, there is still no 3G syncing, unfortunately that part of the beta has been restricted to very few testers. Another unfortunate thing is that the desktop app is only for Mac, at least, for the moment. Any Window users will have to wait until later on in the month before they can get it. Now, something important to know, is that the Wi-Fi Sync 2.0 is a native Mac app not an installable package, which basically means that updating it is pretty simple, but it also means that you have to have it loaded up before iTunes, so be sure to set it to open when you log in!

The iPhone app is obviously a beta, it’s easy to see due to its bare interface, and so Greg Hughes is asking for anyone with UI experience to help develop this app!

If you wanted to use this app, you will have to know the passcode of the Wi-Fi Sync’s desktop app. In order to find said passcode, look in the menu-bar icon’s drop-down menu, once you’ve paired your device, you’ll be given the option to sync.

Apparently, when its syncing it skips the backup of the iPhone in iTunes, but that’s probably because doing backups over a Wi-Fi connection is extremely slow, however, the moment the syncing actually starts, I’ve heard that it’s speed rivals that of when you use the USB!

The Wi-Fi Sync 2.0 also has an Auto-Discovery feature which will find your desktop using your home network which makes setting up as easy as 1, 2, 3! According to the British developer, Greg Hughes, the Bonjour auto-discover integration means that Bluetooth connections are also supported by the sync process.

Now, to get the beta for the Wi-Fi Sync, you should have already purchased it from Cydia, but once you already possess a copy all you have to do is type in the repo: http://dl.wifisyncapp.com/apt to your Cydia sources then patiently wait for it to update your sources! The repo will recognize that the app is owned by you and will install it!

Ok, so if you want the desktop version from the beta website, then you can go ahead and down load it here, but you should be aware that at the moment it’s only going to work with Mac OS X, so if you ended up downloading last nights release, be sure to go ahead and download the new version, because in the first one, the auto-updater doesn’t work!

So how many of you readers plan on downloading the Wi-Fi Sync 2.0? I look forward to hearing what you think, so leave a comment!

Thanks to iPhoneDownloadBlog for all of the great information, since I don’t have the Wi-Fi Sync YET, I wouldn’t have been able to right this article without their help!
