Need a little help here.
I have an iPhone 3GS that currently has iOS 3.1.3 with baseband 05.12.01.
Seems to me like I need to get iOS 4.01 on there and then I can jailbreak/unlock with this useful set of instructions:
How to Unlock iPhone 3GS/3G on 4.0 Firmware
However, how do I get iOS 4.01 on this system? It has never been jailbroken.
I attempted to use iTunes pointing it to the appropriate image for iOS 4.01 for the 3GS and it gave me the "this device isn't eligible for the requested build" message.
Now, I would be fine with "bypassing the overlord" with these instructions
Caching Apple's Signature Server - Jay Freeman (saurik)
by basically redirecting apple's signature server to cydia. But, it looks like those are all for older versions of iOS.
Can anybody suggest a plan? My main interest is unlocking.
Although I would prefer going to iOS 4.1, it seems that that version has not been unlocked yet.
Many Thanks. I know there is alot of info here, but just wanted to let you know I have done a fair amount of hunting for answers....

You can go to 4.1 if you want, just follow one of these guides:

Go to 4.1 as x98car instructed. It's jb'able and with a custom firmware, unlockable AND Apple is signing it so SHSH blobs are no problem.
After (or even now), download Tiny Umbrella
The Firmware Umbrella - TinyUmbrella
and save all SHSH. This is important in case you want to reload an old version.

Agree 4.1 is easy, but maybe you should wait a week and hopefully 4.2 and new tools will be available....

@x98car - Thanks, these are great links. EXACTLY what I needed.
@eyeRobot - Wow, 4.2 came out today. Wow, would be nice to go up to 4.2, but right know, nobody knows when this will be available for jb and unlock.
