Alright, I meant to post this last week, but then after unexpected circumstances I didn't get a chance to, so I'ma post this now to avoid some confusion, which looks like has already started. Any newly bought iPod Touch 3g 8GB will no longer work with Coca-cola's method. You'll get error 28 in DFU, and I can't remember the error number for recovery mode, but it won't sign it anymore. Apple is having the ECID of the 8GB implimented just as strongly as the other 3rd gen models now. Previously, you could still downgrade because it required no checking, and allowed you to run 2g firmware, which allowed the downgrade. Now that Apple has implimented a full ECID check, this is no longer possible. Any iPod Touch bought after the beginning of March may not be able to downgrade.
