This looks like a very good idea. I would like to go ahead and do it but I have one question to clarify before I begin.
After I have followed this tutorial and have collected the information I need, how do I get my 3Gs back out of recovery mode?
When I have Googled, I keep reading things about irecovery.
There is a waaaaay easier method, isn't there?
i tried this guide but got DFU mode which also was ok to get my 3gs' ecid as described in the guide above. to get out of dfu i pressed home and on/off button again and waited for 5 sec. my device rebooted normally.
