TinyUmbrella can return your jailbroken iPhone to a previous update, reversing any damaging that the jailbroke did and allowing you to restore to a previous firmware update, or even back to default. You can’t return a jailbroken phone to the manufacturer, nor can you take it back to the store, but your money isn’t lost just yet as the TinyUmbrella, a unique and simple program, can save you from losing a small fortune.
If you have just paid a small fortune for a brand new iPhone which you have then jailbroken, it can be a rather crushing experience if the phone doesn’t run as well as it should or if there are a number of problems with the firmware.
