Problems haveing both new ipad and 2

[katt5]

Have 3 iPads all on same iTunes account. My husbands, listed as his iPad, my iPad 2 listed as my iPad 2 and new one with ipad3 in the name.
All new apps are only installing on my ipad2 . Even here, I tried to log in on ipad3 and it said not right log in but no problem with the ipad2.
What gives?

I guess that every iPad/iPod that is using the same iTunes account have to be called the same thing.
