I jailbroke my iPad 4 64 Gig Wifi + 3G with evasi0n7-win-1.0.2. I had upgraded to IOS 7.04 OTA and didn't have any problems with the J.B. I didn't restore to factory settings first.
At first I was upset because Cydia was locked in portrait mode, but as soon as I updated some stuff and reloaded, it is back in normal landscape.
