That is because you can't just simply go back to 2.1 after you updated to 2.2. Can't do it.

Connect it to iTunes and just restore it. It will be 2.2.

You have to put it in DFU mode.

Follow these (http://www.iclarified.com/entry/index.php?enid=1034) instructions.

I don't do it that way.

I connect to iTunes, turn off my iPhone, then do the both buttons for 10, home button for 10 - which works.

I may try it this way next time as it seems to be "quicker". Though my way equally works every time.
