A new version of TinyUmbrella has been released to help protect your baseband from being changed during a iPhone 4.1 firmware update. It is still recommended that should you wish to jailbreak and unlock your iPhone do not update to 4.1 yet. Here are the latest features:
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)
