Hi i have an ipad2 version 5.01 JB. I want to upgrade to 5.1.1 and then JB. But it have mention that that the following model can only be JB. e.g 1,1-2,1-2,2 . how will i know which model i have.
The recommendation is to get the free app Linpack (from the App Store). The first screen you see after opening the app wil show you what version of iPad you have.
