Download links and some notable features in TinyUmbrella 04.02.09 after the jump…

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)
iPod Touch 4G 4.1 support

IMPORTANT: Do not update to iOS 4.1 if you wish to keep your unlock and jailbreak. The baseband protection only applies to iPhone 4. It’s a small yet very important note. 3G and 3GS phones are excluded.
