Note: This only applies to iPhone 4. Tested successfully for iPhone Lock 4 IOS 4.0 -> 4.2.1 Modem Firmware 01:59:00

Tools needed:
- TinyUmbrella 4:21:07
- IOS 4.2.1 download from Apple's original
- RC Greenpois0n 5b3 (Mac OS) or RC Greenpois0n 5b2 (Windows OS)

Do the following steps:

Step 1: Run to save SHSH TinyUmbrella 4:21:07 4 iPhone 4.2.1 (4.2.1 SHSH required before it)

Step 2: Run the TSS Server

Step 3: Run iTunes and select Restore to Firmware 4.2.1 (Restore not update it)

Step 4: Restore is complete, you will see error 1013 - can not remember to use TinyUmbrella "Exit Recovery" after seeing this error.

Step 5: Run Greenpois0n RC 5b3 (Mac OS) or RC Greenpois0n 5b2 (Windows OS) and follow the instructions to put the iPhone into DFU mode to jailbreak Mode

Step 6: Insert sim to activate the network with iTunes. Loader running on iPhone to install Cydia (If you run the loader, but not found a place to install Cydia, then check your wifi and try it again because of Greenpois0n server can be overloaded). Into cydia and install update 1.2 for unlock ultrasn0w. Enjoy

Bro I think will be better to find CUSTOM FIRMWARE v4.2.1 with old modem version and to add to your topic. It will be great because this file will save our time.
If you can't find this file 3,1 v4.2.1 with modem version 01.59.00 tomorrow I will share it.
