Messed up trying to upgrade 1.1.1 to 1.1.3!

Think I may have messed up... I upgraded my jailbroken unlocked 1.1.1 to 1.1.3 thru itunes so I could then use Ziphone but now itunes just says this sim card isn't supported and I can't get any further! Anyone know what I've done wrong please?

You haven't done anything wrong.

Restore your iPhone to 1.1.3 using iTunes. You can leave the Sim you want to use in the phone. iTunes will tell you your Sim is not supported but that's fine.

Once that is done quit iTunes. Put your phone into recovery mode and run ZiPhone.
