TinyUmbrella Updated Ahead Of iOS 4.1 Release; Includes Baseband Protection For iPhone 4
A new version of TinyUmbrella, the tool that allows you to take backups of SHSH blobs (ECID SHSH) has just been released in anticipation of iOS 4.1, which is expected to be released tomorrow, September 8.
The new version of TinyUmbrella will also protect your iPhone from baseband updates when you update it with iOS 4.1.
The ‘baseband’ is the generic nickname given to the internal components of the iPhone that handle the phone calls and Internet access. This ‘baseband’ is a tiny and unique independent computer system that runs inside your iPhone, it is separate to the main system that handles the applications (such as email and google maps) and it talks to the main part of the phone over an internal communications network.
Think of it like a cable modem or other peripheral that is attached to your home PC that needs occasional updates. When a software update is released and presented to you within iTunes the baseband is sometimes updated (to fix bugs or add new features).
Based on the beta version and Golden Master of iOS 4.1 that has been seeded to developers of iOS Developer Program, iOS 4.1 also includes a baseband update. So users who want to unlock their iPhone as there is no software method available currently that can unlock the new baseband included in iOS 4.1, which is where TinyUmbrella can be very useful.
The new version of TinyUmbrella includes the following new 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)
iPod Touch 4G 4.1 support

Note: If you have jailbroken your iPhone then Cydia will automatically store the SHSH blobs (ECID SHSH) when you launch it so you don’t need to use TinyUmbrella to take a backup.
