That's the obvious answer to that question, but there were several versions after 4.0.5c that were compatible with ios 4.3.3. Why would it be using such an old version of PKGbackup. I can installed the cracked 5.1.6 version no problem on this ipad, as well as the free 4.3.12. I get that this is there for backwards compatibility, but I get the impression it thinks my ios is older than 4.3.3.
This is right from their website:
Q.I recently purchased pkgbackup. When I open Cydia, it Shows me the latest Version, 4.2.10, As installed. But when opening the program itself, it says Version 4.0.5c in the Upper right corner.
R.All new features of v4.2.x for ONLY available on FW 4.x+
If you really pay attention to what its say, it says the 4.2.x should work on ios 4.x+. ios 4.3.3 should fall under that category, and get the 4.2.x features, not the 4.0.5c features. Would you agree or am I missing something there?
