3.0 ECID reconized as 3.1

3.0 ECID reconized as 3.1 in cydia and umbrella, when the firmware is 3.0 any cause for this

Cause is Apple is no longer signing 3.0 ECID files. You too late to get them.

But I am saveing it from a 3.0 3GS

Cydia can only save ECID files for currently released firmwares. What cydia does is submit an ECID file request from the the apple server (since these files have to be signed/verified by apple) which is specific to each phone and the only file that can be requested is for the current apple firmware, no matter what firmware version you have on your phone.
