Hi, I was runnning firmware 4.3.3 and tried to upgrade to Ios 5 and jailbreak it.
I used this link :

But it got me into big trouble !!!

I managed to upgrade to 5.0, do the jailbreak but after that I wasn't able to call because it said No Service.
The problem seemed to be that the baseband was also updated to 04.11.08.
I tried do downgrade to 4.3.3 with the SHSH files but that didnt work really good. Then I did an official itunes ios5 upgrade and still the same problem,
after that i got back to 4.3.3, than back to official 5.0 and then i still had baseband 04.11.08, it seems you can't downgrade that !

So once i was in 5.0 for the last time i just tried to call 7800 , hung up and after a minute or something i received my operator TELENET !!!!
I just chose a random number, don't know if an other number would do the same.
so i'm back able to call and receive calls but on baseband 04.11.08 no idea how i did it exactly but I don't know if i'm going to try to jailbreak again, if i'm getting the same problem.....
Someone had the same problem and knows how to jailbreak it good ?

I think it's because you used that link to upgrade to ios5. Do it threw iTunes. Then run redsn0w to jailbreak.

If you are on 5.0, use our tutorial here to jailbreak it - http://www.iphoneforums.net/forum/h...-ios5-tethered-using-redsn0w-beginners-25943/

As regards the baseband, you are on 04.11.08 for good now. It can never be downgraded.

If you want to downgrade the phone to 4.3.3 you MUST have previously saved SHSH Blobs for 4.3.3. Look at our tutorial here - http://www.iphoneforums.net/forum/h...ave-your-shsh-blobs-using-tinyumbrella-18924/

Hi, i did the semi tethered jailbreak yesterday and now everything works fine!!!
I am on baseband 4.11.08, i have no idea how i unlocked it.
Try calling a number and turn On airplane mode then, and back of, maybe that helps.
Greetz!
