Thanks for all your great work on this

I've just installed Bootlace 2.1 and used it to do a fresh install of both OpeniBoot and iDroid. When I boot to iDroid, it gets stuck on:
radio: reading baseband nvram...done
I've had iDroid 1.0.3 working before now - but have since upgraded to iOS4.1 and did not reinstall OpeniBoot after the upgrade. I deleted my old iDroid files before using Bootlace.
Any ideas what I might need to do to fix this?
iPhone 3G, iOS4.1, jailbroke with redsn0w 0.9.6b1 iirc
