Upgrading 3GS from 3.1 to 4.0/4.0.1/4.0.2/4.1/4.2?
Kinda a sucker at all this JB'ing stuff so would appreciate some help. I've got a iPhone 3GS with iOS 3.1 and baseband 05.11.07 with old bootrom. I've starting to have an erge to upgrading to iOS 4. Which version of 4.0/4.0.1/4.0.2/4.1/4.2? would be the optimal for me? Which version can I upgrade to and still remain untethered? Don't need to be able to unlock it.

I'm on this same situation, I won't upgrade my baseband, I won't like to be locked forever.
I try to upgrade to 4.1 like 3 weeks ago and received the 1600 error so I still stocked on 3.1.2.
I will wait til next week to do the upgrade maybe to 4.2.1 but only if I don't have to do the ipad treak

As you depend on unlocks, you would have to install the custom ipsw's anyway, so I do not see the downside.
But most importantly. If you are ALREADY UNLOCKED, there is no need to do the iPad trick. Simply use redsn0w to keep your baseband as is and make a custom firmware for the new firmware you wish to install.

Tool User...........Blackra1n (UltraSn0w)
I want upgrade to 4.2.1 so let me recap to be clear.
Go to DFU mode
make a restore with iTunes and 4.2.1
Jailbreak with Redsn0w 0.9.6 Beta 5 for Windows
From Cydia install Ultrasn0w 1.2
Sync and restore from my backup
Enjoy my iPhone?.
If that correct?
