I have an iPad 1 with the most up to date IOS which is 5.1.1
I went to the iTunes store and did a search from Dropbox, which I downloaded.
When I try to install it from iTunes on my PC it fails. No errors are displayed. When I click the INSTALL button it changes to WILL INSTALL. I click and drag the app from iTunes to my iPad screen and it does appear. I click sync and it disappears from the iPad's desktop.
I googled the problem and all the posts indicate that I need to have iOS 7. My iPad 1 cannot be upgraded past 5.1.1
How can I get dropbox or something similar installed on my iPad?
