All you iPhone 3gs GURUs,

I have a totally weird problem with jailbreaking by 3gs and would appreciate any assistance provided.

Below is the chronological order of things that I did to my iphone 3gs
1. Bought my brand new iphone 3gs (Bootrom - 359.3.2; firmware - 3.1.2) from a seller in Dec '09 and JB, unlocked it with B1ackrain and used my 3gs with no issues for almost 6 months with T-Mobile
2. Tried to upgrade my 3gs to a jailbreaken os 4.0 using pwange tool (snowbreeze) using Windows via the steps listed in redmonpie.
3. Biggest mistake done - I forgot to save a copy of my firmware in Cydia
4. As multiple updates to JB OS4.0 failed, i was frustrated and upgraded to OS 4.0 directly from Apple (the dumbest thing I did)

Now my iphone 3gs is locked to AT&T, due to which I had to take a AT&T connection.

Though I have read this forum and other forums multiple times, can some one tell me if there is a unlock method/tool available for my 3gs Os4.0?
If no alternative is available currently can someone tell me if there will be a solution for me to unlock the os 4.0 in the near future? I will be leaving US shortly and would like to use my iphone 3gs after unlocking.

All you GURUs please let me know if I should keep my hopes up or is my iphone good for nothing once i leave US?

amirdeula - Dont upgrade from Apple directly. Snowbreeze does have an option of "cooking" the OS4.0 and installing it as an jailbroken os. But this does not seem to work for most of the people.

Before you even try upgrading save your SHSH in Cydia so that if anything screws up you can downgrade and still unlock your 3gs. I missed to save my SHSH and hence could not downgrade and now am stuck with a stupid AT&T connection.

have you installed tinyumbrella? you can look at past firmwares to see if Cydia saved your shsh blobs. I misstakenly up graded to the new ios 4.0.1 from a 3.1.3. I was with out T-mobile for a month. I looked up my shsh blobs on tinyumbrella and got them from Cydia. I was able to downgrade to 3.1.2 FW and cooked a new FW 4.0 using snowbreeze 1.6.2 for my 3GS.

im pretty sure the new ultrasnow will unlock your phone, if you go to Jailbreakme.com, and jailbreak yur device, then go to cydia and add if its not already there the repo: repo666.ultrasn0w.com make sure the o in snow is a zero and not an o, that shud work

You have to restore to 4.0 again to fix the problem.

Not a guru but another person who enjoys JB-ing. I agree, if you do not have your shsh blobs saved, just go to jailbreakme.com since your firmare is 4.0. It never hurts to down load tinyumbrella. You might be surprised.
