How To Jailbreak & Unlock Firmware 4.3 on iPhone 4 & iPhone 3GS

This video tutorial will show you how to jailbreak and unlock your iPhone 4 or iPhone 3GS on firmware 4.3 using Sn0wbreeze and Ultrasn0w. Sn0wbreeze will also enable multi-touch gestures on 4.3.

If you have an iPhone 3GS with an old bootrom, then this jailbreak is untethered. This jailbreak is tethered for the iPhone 3GS (new bootrom) and iPhone 4.

Add this source to Cydia and install Ultrasn0w (if it has not already been added): repo666.ultrasn0w.com

Ultrasn0w will unlock the iPhone 4 and iPhone 3GS on the following basebands:
01.59.00
04.26.08
05.11.07
5.12.01
5.13.04
06.15.00

Download Sn0wbreeze v2.3b4: http://hotfile.com/dl/110970596/fe3ea9f/sn0wbreeze-v2.3b4.zip.html

Download the 4.3 firmware for your device: http://www.felixbruns.de/iPod/firmware/

Note: If you rely on an unlock to use your iPhone, then you will need an official SIM card in order to activate the phone.

If your device has a tethered jailbreak, then you will need to boot your device with iBooty after jailbreaking. Watch this video to boot up your device: http://www.youtube.com/watch?v=oBMjNHDYezk

Hello, i have a few questions.

I am on firmware 4.0 right now. Do i have to upgrade to 4.1 first or can i do it this way instantly to 4.3?

Also, do i lose all my apps and iphone contacts if i do it this way?

I've never jailbroken and unlocked firmware on my iphone myself, i do have a jailbroken iphone right now. Thanks
