Tiny Umbrella is has been updated with iOS 4.3.5 support and the ability to update your iPhone 4 baseband.
I'll probably regret this but this newest version of TU (5.00.07) will allow you to choose whether or not to update your iPhone 4's baseband.
This new feature comes with a catch:
1. First, the version you WANT to restore to and the version Apple is currently signing must BOTH have the same baseband. This is important or else the baseband update will not work and you will get a 10xx error and need to use fixrecovery. (Works for iPhone 4 - will not work for iPad 2)
2. Second, you need to realize that checking the box WILL UPDATE YOUR BASEBAND.
3. Third, I'm working on a simple tool that will allow you to create a pseudo-custom firmware mixing a new baseband with an older iOS version (one that is jailbreakable for example). This feature exists in the TinyUmbrella rewrite but does not yet exist in the older codebase. SORRY! I'm working on it!
You can download TinyUmbrella from the link below and find instructions on how to use it here: (Mac, Windows)
Reminder: Don't update your baseband if you want to unlock!
