I am an iPad 1 user on 5.1.1 JB and have wanted to upgrade to ipad3 for a while but kept procrastinating. Now that the 4 is out, should I get the 4? Or quickly find a 3 from my local store? My concern is mainly on JB which I cannot live without. The 3 comes with 5.1 as far as I know and that can be JB-Ed. The 4 has two issues, a new chip to hack, and it comes prob with ios6, which can't be JB-Ed on anything known for quite a while. Any thoughts?
