Does the "last compatible version" method behave differently in iOS 5 vs 4.2.1?
I have a 4.2.1 device and have downloaded several apps with the "last compatible version" technique, without needing to pre-purchase them on a desktop PC or a newer iPod. Now I see lots of people with 1st generation iPads (ios 5.1.1) complaining that they can't download the Facebook app.
Thanks to Lllaass, I read this note from Apple which seems to have the solution: they have to buy it on a PC first. (The note specifies iOS 4.3.3 or higher) The big downside, then, is that for paid apps, you have to be sure that there is a compatible version!
With my 4.2.1 iPod, I would choose the app, enter my password, and then be told whether or not there was a compatible version. I haven't actually bought any paid apps with this technique, though.
So how's this for a summary:
iOS 3.1.3 devices cannot use "last compatible version" at all.
iOS 4.2.1 devices can download "last compatible version" apps directly.
iOS 5 users need to buy the apps on a PC or newer device before they can download them with "last compatible version."
Does this sound about right?
