I'm on an iPhone 4 v4.2.1 with baseband 03.10.01 right now. I'm going to 5.0.1 with a jailbreak and unlock, so I'll keep my current baseband version using redsn0w. Is there any reason to update the baseband, and if so, how would I do it?

Updating the bb is the easy part. Preserving the bb is the hard part.
FYI, you can't software unlock with your bb.

Ah ok, I thought ultrasn0w would. So can I update the BB and software unlock?

Your current baseband is not unlockable via software. However, if you update to iOS 5 you're in an even worse position. The reason I say this is because your current baseband is unlockable via the Gevey SIM card. I would preserve the baseband just so you atleast have the option to use a Gevey in the future if you ever needed it.

Good point.
You might as well preserve your bb, so you can use gevey for vacation or whatnot.

Quick question. I am on 4.2.1 with 1.59.00 BB. I want to preserve it, all I do is use redsn0w and create a custom IPSW and use that custom IPSW to update my iPHone 4 correct?

Okay thanks guys.

Just use pwnage - it's much easier.

Thanks, that makes sense, didn't know only unlockable iphone4 baseband was 01.59.00.

Some people consider pwnage difficult to use. However, pwnage is the best option, imo.

Is there an actual difference between Pwnage and just using redsn0w to create a custom IPSW? (advantages / disadvantages)

Keep in mind the team hasn't updated pwnagetool to solve the launchctl issue redsn0w had.

I'd avoid that program like the plague right now.

Pwnagetool seems more and more useless as its main features (baseband preservation, hacktivation) are in redsn0w.

Also, pwnagetool can't stitch shshs and aptickets to firmware either making it even more useless. I don't see a need to create a custom firmware that can't be restored to when it is no longer approved of by apple.

Correct me if I'm wrong.

The only real advantages left to pwnagetool are: custom root size partitioning and the ability to preinstall cydia programs in the firmware directly. You could do this then take that firmware over to redsn0w and stitch your shsh apticket blob to it. You'd then have the ultimate file that would preserve unlockable baseband, be preloaded with cydia software, hacktivate (if you need it), and be signed so it can be used even when it is no longer the current firmware.
