Have you tried recovery mode : http://support.apple.com/kb/ht4097 ?
Error -1 has been mentioned a few timeson here but I can't remember if there is a general fix for it - are you close to an Apple store ?

yes, I've been through the recovery process about 4 times.. at the end of it, it tells me it can;t restore, because of that error. But can't find out what that is.
I am not near an Apple store, but I've asked for a telephone callback, so maybe that can help. It's irritating, because I wasn't troubled by anything in 5.1 that I was aware of!

Next time before you do any upgrades especially for devices running proprietary software, don't just conduct the upgrade for novelty. If your current version works, leave it there. There are why some version archiving websites still exist, for a good reason when it comes to software.
Bottom line is the nature of iOS updates such that it is run in an arbitary approach (not sure if I used the right word) because rollbacks cannot be triggered. Rollbacks serve a purpose of reverting your device to its last healthy state, iOS doesn't do that.
There are people out there with bricked devices from upgrades bricked the device unintentionally/intentionally because the device doesn't revert back to its last healthy state when it is experiencing an error preventing the update from proceeding. My personal advice is don't peform an upgrade unless you really have to.
That's the last thing I'll look at - at least for me.
Until then, seeking help at an Apple Store would probably be the best choice you have currently.
