[HOW-TO] - Downgrade iPad 2 GSM / CDMA From iOS 5.0.1 To iOS 4.3.3 Using TinyCFW

• Notcom, the developer behind TinyUmbrella released a new tool called TinyCFW. 
• What TinyCFW is that it prevents any errors and looping when downgrading iPad 2 GSM / CDMA or iPhone 4 GSM / CDMA from iOS 5.0.1 / 5.0 to iOS 4.3.3 to get their jailbreak.
• The reason why many of you might want to downgrade their iPad 2 from iOS 5.0.1 to iOS 4.3.3 is that because there’s no any jailbreak available for iPad 2 except Comex’s JailbreakMe 3.0 which only works on iOS 4.3.3. 
• So if you’re one of those who accidently updated to iOS 5.x, having iOS 4.3.3 SHSH blobs and want to downgrade back, TinyCFW makes this process easier by creating a custom firmware that will be able to be recognized by TinyUmbrella so that the device can be downgraded.
• iPhone 4 reasons might want to downgrade back to iOS 4.3.3 so that they get untethered jailbreak which is only available on that version. 
• However, pod2g and Dev-Team already released an untethered jailbreak for all A4 devices so ther's no reason to downgrade.

What TinyCFW is:

• It will modify an existing ipsw for an ipad2 gsm/cdma or iphone4 gsm/cdma
• It WILL modify the ipsw TO UPDATE YOUR BASEBAND TO THE LATEST!
• It will create an ipsw that you can use with TinyUmbrella AND iTunes to restore to a version of iOS that you have SHSHs for.
• It is primarily for iPad2 with a baseband OR iPhone 4.

What TinyCFW is NOT:

• A jailbreak
• An unlock
• A tool to protect your baseband.
• A tool that will restore your device to any firmware
• A tool for use with iPhone 3GS, iPhone 3G, iPad, or iPhone 4S
