Finding old versions of iOS apps (for 5.1.1 on a 1st Generation iPad)
my daughter showed me an easy way to install the older Apple store apps. you simply log onto the apple store using a computer (without the iPad connected). find &amp; download the software to the library on that computer. once it is added to your library, goto the app store on the iPad &amp; install the software...
since the newest version won't work for the iPad, it will ask you if you would like to install the latest compatible version.
this seems to work for 85% of the apps out there (as long as there was a prior compatible version).
