Took the length of the Spain/Honduras match (including half time, obv) - full backup (thought it had stalled at one point. Apple REALLY has to work on its user feedback), install, reboot to factory settings, restore from backup (lots of apps including a couple of biggees and loads of music and vids).
Seem to have disabled my pinlock, but that might be 'cos of the new system. Not checked yet.
Then did a carrier update which seems to have beefed up my signal no end (touch wood).
Folders are lovely.
