Posted by ItouchHelper7 Monday, 28 February 2011

This Is A Very Easy AND SAFE Jailbreak Tutorial That Will Teach You How To Jailbreak Your iPhone 4, 3Gs, 3G, Verizon iPhone And iPod Touch 4th, 3rd, and 2nd Gen MC Models On 4.2.1 Firmware, Also iPad On 4.2.1 using Redsn0w jailbreak..


You can install the bigU Movies app from Cydia or go to (www.thebigu.info) from non jailbroken idevice or computer if you would like high quality movies to stream or download directly on to your iPad, iPhone or iPod.

Cydia and Safari don't crash when you open them like they do from other jailbreak videos that didn't explain things completely.

Works On The Following iDevices:
iPad *Tethered*
iPhone 4 *Tethered*
iPhone 3G *Untethered
iPhone 3Gs Old Boot Rom *Untethered
iPhone 3Gs New Boot Rom *Tethered*
iPod Touch 4th Gen *Tethered*
iPod Touch 3rd Gen *Tethered*

The notion of a "tethered" jailbreak is pretty new to many people, so here's a quick rundown on what to expect:

1. If you're on an iPhone3G, old-bootrom iPhone3GS, life is easy. redsn0w installed an untethered jailbreak and so nothing below applies.

2. "Tethered" does not mean you cannot boot at all without PC/Mac assistance. If you have not installed any tweaks that hook into important programs like SpringBoard or CommCenter, your device will actually boot. However, jailbreak programs like Cydia won't work (and Cydia may still have a white icon). Also, certain built-in apps that had to be moved by Cydia will fail (Safari being the most noticeable example).

3. If you've installed MobileSubstrate tweaks that hook into SpringBoard or other important programs, your boot will actually fail (you'll get stuck at the Apple logo). You need to use redsn0w to "Just boot tethered right now".
