My archive collection that I collected over the years and sorted with my own metadata scripts so that I see on what iOS the IPA runs. I also collect and archive multiple versions of the same IPA. (1.00, 1.01, etc.) Mostly untested, only checked if the file is structured as a valid IPA format and contains not damaged metadata in it (so that it is installable). You can see the raw parsed metadata in the *.txt files that lie next to the IPA file/s.  

Ask in comments when you need a specific IPA.

I have multiple source/s that have many legacy IPAs, but with the catch that it requires a premium account. I will add them to this collection, when found. (I dont have that much premium traffic, so only smaller apps please)
