The latest version of TinyUmbrella has been released and it’s compatible with iOS 4.2.1. TinyUmbrella lets you save SHSH blobs from compatible hardware, allowing you to upgrade your iOS version while maintaining older versions of baseband.
TinyUmbrella is of particular interest to those who want to unlock their iPhone, if you are looking to unlock your iPhone you should save your existing iOS 4.1 shsh blobs before downloading and updating to iOS 4.2.1. Here’s why this matters, directly from the TinyUmbrella developer:
Do not update to 4.2.1 for the baseband protection. TinyUmbrella is no longer able to kick you out of recovery for that version. TinyUmbrella still works for prior versions and will be able to restore and kick you out of recovery for those versions but 4.2.1 has a baseband version check that will stop your device from booting if your baseband was not updated.
