Downgrade 5.0.1 / 5.0 to 4.3.3 on iPad 2 3G (GSM / CDMA) with TinyCFW [How to Tutorial]

if you are an iPad user then you must be well aware of only unthethered jailbreaking solution made available yet for iPad 2 called JailbreakMe 3.0 released few months ago. But unfortunately some users having iPad 2 have accidentally upgraded their devices 4.3.5 / 5.0 or 5.0.1 as a result of which they lost Untethered jailbreak on iPad 2.

Keeping in view of above, a famous and genius iPhone developer Notcom has developed a brand new tool called TinyCFW which allows users with iPad 2 3G (GSM / CDMA) and iPhone 4 devices to downgrade from 4.3.5 / 5.0 or 5.0.1 to iOS 4.3.3 in order to get back the untethered jailbreak.

From Developer:

What TinyCFW is:

• 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.
