IOS USERS PAST/PRESENT: I need your help

Hi. I need a favor from you.

1. If you're not on iOS right this minute, but you were on iOS at some point in the past year or so, then I need your help.

2. I have figured out how to download an older version of instagram successfully. However, I need the actual iOS app file in order to complete this. I have not backed up my phone very recently, and do not have a new enough version. With the iOS I am currently on, I cannot use a version older than 7.20.1.

SO, this is where you all come in hand.

I need version 7.21.1 for what I'm trying to do.

This is how you search your computer to see if you have this file if you don't know how:

1. on your mac, open a Finder window
2. searchbar
3. type in "Instagram .ipa"
4. if you have backed up your iphone, .ipa files will show up. I am very particular about which version I need. However, if you have version 8.0 - 8.5.2, i'll take it. Anything after that I do not want.

Reply to the thread if you have the 7.21.1 file. Thanks!!!!!!
