iPhone 3GS Activation problem
Yesterday I bought an iPhone 3GS on 4.0.1 software. After erasing all the data and setting it asked me to put a valid sim and connect to iTunes so I did that. It doesn't want to activate and asks me to upgrade to 4.1. I don't want to do that because I want to unlock it.
Erasing all data and settings is not recommended. It is overkill in most cases. Most people don't seem to understand that this erases the OS as well, so you have to restore afterwards.

Once you identify your ECID use TinyUmbrella - will backup your 4.0.2 SHSH - before it is too late. Check to see if the previous seller saved any SHSH for 4.0.1 or lower.
If you can't get any SHSH for < 4.0.2 then your only choice is to restore to 4.0.2 and try and activate to use as an iPod only (until a jailbreak is released for 4.0.2)
There are plenty of threads explaining how to use a phonebook SIM to activate.
DO NOT restore or upgrade to 4.1, this will destroy your ability to unlock (maybe permanently)
