Any question answered...

Forggedit. Just been round this loop all this week - all the progs (£19.99 FFS) and a bunch of blokes in town, plus the pukka shops. There is no unlock for 4.1 yet, despite what they will tell you to get yer money on line. You can only roll it back to 4.0 and go from there. You can jailbreak 4.1 (done that - great), but not unlock.

Have you saved your SSH blobs? If yes, downgrade.
