Ok, so I have screwed up on 1.1.3 because of the FWChanger and can't boot the iPhone. I need it for tomorrow so I have downloaded ZiPhone and was wondering if these steps are correct :

1) Restore my OTB 1.1.2 (currently on 1.1.3 using the previous version of ZiPhone) to 1.1.4 using iTunes.
2) Use ZiPhone to do it all and get on to 1.1.4

Is this safe?
