Back in late June/early July, I reviewed an app called Wi-Fi Sync for jailbroken iPhones. You can find my revised version of the review here. Originally this seemed like a pretty neat app. It's a bit pricey for what it does, but it did it well.
Now I've been having several issues with iTunes over the past 2 months. I couldn't restore or upgrade firmware (it would hang up at the very end and leave all my devices in never ending recovery loops). To my dismay, it also broke backups within iTunes. I found this out after I wiped one of my devices and then noticed my last backup had been 2 months earlier. In frustration, a buddy on Twitter (@snoslicer8) asked if I by chance had Wi-Fi Sync installed. And without a doubt, that was the problem.
Needless to say, click along to see how to fix these issues if you're having problems with iTunes and you've previously downloaded W-Fi Sync. Odds are, it's the culprit.
You'll need to complete these steps exactly in order. If you have already uninstalled Wi-Fi Sync and that didn't seem to solve the problem, re-install it and do these steps completely in order. Odds are you didn't complete the first step before uninstalling and that can cause your backups to still epically fail. So after you re-install, reboot your Mac before continuing.
*Side note: I am on Mac OS X Snow Leopard (10.6.4). I do not know if this effects previous versions of Mac or PC. If you know or have any input, please feel free to leave it in the comments for future users who may have the issue.
Re-enable backups via Wi-Fi Sync
This is why I said to re-install if you had already uninstalled. You'll see the icon for Wi-Fi Sync in your top taskbar, it looks like a tiny iPhone like below.
Click that icon to get a drop down menu, you'll see one like the one below. If disable device backups is checked, UNCHECK it. For me, device backups were disabled by default. If you don't do this before uninstalling, you will still have issues with backups even after uninstalling.
Only after you've done this, will you be good to uninstall.
Uninstall Wi-Fi Sync
A lot of users were wondering how to uninstall Wi-Fi Sync. I'm not quite sure why the developer did not include the uninstaller in the bundle, but you'll have to go here to download the uninstaller for Mac. Download that and run the terminal app. It may prompt you to enter your admin password.
Reboot your Mac
After you reboot, your problems should be solved. To make sure, simply open iTunes, connect one of your iDevices and sync it. It should saying backing up, which it didn't say before. Or another way to know is after you sync, go to iTunes ---> Preferences --> Devices and look to see if you have a new backup. If you do, you should be good to go. If you are still having issues, leave a comment below and we'll try and help you out.
Thanks to @snoslicer8 for helping me out with this one! And as my revised review states, I can't recommend this app until the developer does something about this. This is app is not worth paying for when it breaks core functionality in iTunes. So until it's resolved, I can't recommend anyone pay money for this application. I tried contacting the developer over 2 weeks ago to no response. I attempted to contact him on Twitter as well, to no avail. I can't seem to find a workaround other that completely uninstalling the app, and the issue seems pretty prevalent in several forums and boards. If anyone else found another solution, let us know!
