2. Download and install iBackupBot on your computer.
3. Disable automatic syncing in iTunes by going to Edit > Preferences > Devices and check Prevent iPods, iPhones and iPads from syncing automatically.

6. Select the latest backup you have on the left side.
7. Open the Library/Preferences/com.apple.mobilesafari.plist file. Click Cancel on the dialog that appears afterwards.
8. Scroll down to the bottom of the file and insert this line right above the line that says </dict>
<string>Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11</string>
Be sure to click the Save disc icon, then close the file.
9. Check the box next to Library/Preferences/com.apple.mobilesafari.plist, then click the Restore button.
