Version 4.02.09 | Release Date: 2010-09-07 | Download

Let me preface this by saying that it is important that you do not update to 4.1 if you wish to keep your unlock and jailbreak.
I've updated TinyUmbrella in anticipation of the imminent release of iOS 4.1. Here are some notable features. (Sorry I have not finished the changes I mentioned previously as these features I felt were VERY important with 4.1 coming)
Baseband Protection - Updating to 4.1 using TinyUmbrella will protect your baseband from update. THIS ONLY APPLIES TO IPHONE 4!!!!! If you have a 3G or 3GS and you update to 4.1 your baseband will likely be updated.
SHSH Retrieval from Cydia - If you don't have your SHSH locally, TinyUmbrella will request them from Cydia on-demand; allowing the restore to continue
Automatically point hosts to Cydia - Once you close TinyUmbrella, it points your hosts file to Cydia (for further baseband protection and update/restores without TinyUmbrella)
I hope it helps.
EDIT: I've also added iPod Touch 4G 4.1 support :)
