Hi,

Iíve got a 3gs 16gb jailbroken and network unlocked with ultrasnow. About a week ago I was having a few problems with it so decided to delete all personal info.
Now my iphone is still stuck in boot mode and I am using my old phone because I donít want to network lock the phone by upgrading to 3.1. (Therefore also updating the baseband)
Apple will not let me reinstall 3.0 and I have not got my ECID SHSH on file.
My Question is
Is it already too late as I have not got my ECID SHSH on file. So I might as well upgrade to 3.1? Or leave the phone on the shelf a bit longer in the hope there is another way to get back version 3.0 without ECID SHSH on file?
