Download TinyUmbrella 5.11.00b is very important step in using iPhone or iPad. You can easily save SHSH blobs of iOS 5.1.1 and use it for future downgrade.

A lot of files are changed during updates and there arise a need to have files of lower iOS version for downgrade, for example. As I began talking about iOS downgrade then a topic would be about SHSH blobs and TinyUmbrella 5.11.00b that would be needed to save SHSH blobs.

Sendmodem is a tool that can access iPhone’s and iPad’s 3G baseband (modem) through /dev/tty.debug port without the need to disable the CommCenter. The original code for SendModem was taken from iPhone’s SMS app and its output format was slightly modified by sendmodem developer PmgRiPhone. Usually the modem or baseband is accessed through Minicom with sending commands to /dev/tty.baseband. Minicom needs CommCenter to be disabled in order to work normally. After you’re done using Minicom you have to enable the CommCenter again.
Here’s the instruction how to check your iPhone’s lock state (baseband unlock status) using Minicom or other tool that can send AT+ commands to your iPhone’s baseband. Use this method if you want to know if your iPhone is unlockable. To get the info about your SIM state and unlock state do as follows:

Here’s the list of tools which can communicate with your iPhone’s baseband. Those are Minicom, sendmodem and igsm. They are text-based Unix systems which can send commands to the baseband (or modem) of iPhone. The difference between them is that Minicom needs CommCenter to be disabled while communicating with baseband. Sendmodem and igsm don’t require the CommCenter swith off in order to work properly. They execute the AT+ commands directly from the command line. Let’s take a closer look on each of the tools.

IDA Pro is most powerful and most developed disassembler available today. It’s multi-platform, multiprocessor interactive disassembler. Its main task is to convert binary executable program into assembler text. That allows you to browse through the source code of executables, reverse engineer for getting the internal source code text of the file.
Today is the big day for iPhone 4S, iPad2 and iPad 3 users. New version of RedSn0w 0.9.11b1 has been recently launched by iPhone Dev Team. You can use this updated tool to downgrade iOS 5.1.1 to lower version for untethered jailbreak. If you are A5 device user then you know that there is no untethered jailbreak for iOS 5.1.1 and 5.1. So you can downgrade your iOS to 5.0.1 and use Absinthe to jailbreak it. However I have to tell you that iPad 3 can’t be downgraded to iOS 5.0.1, only to 5.1 (but there is tethered jailbreak for it.)
Great news has just come from MuscleNerd. He says that updated RedSn0w 0.9.11b1 was released by iPhone Dev Team specially for A5 (A5X) devices(iPad 2, iPad 3 and iPhone 4S).
