Baseband 05.10.01 - how to downgrade?
I have an iPhone 3GS and got the OS 3.1b2 installed several days ago.
Now I know this was a baaaad decision since it upgraded the baseband to 05.10.01.
I was successfully able to downgrade the iPhone back to OS 3.0 and it's now jailbroken with redsn0w. Of course I tried Fuzzyband 3.1b1 for downgrading the baseband but it's not possible. Anyway... My opinion is that when I can upgrade firwmware than there is a way to downgrade it.
I'm thinking about trying to install the iPhone OS 3.0b5 for the 3G on my 3GS because I know that the Beta 5 came with baseband 04.26.08 and hoping it might overwrite it. And than install iPhone OS 3.0 and jailbreak it again. I do have access to a 2nd iPhone 3GS with baseband 04.26.08. I don't know but maybe this could be helpful?
If someone of can give some positive and helpful input, that would be greatly appreciated.
