Hi - we are trying to repurpose our old iPad 1 for my mother-in-law. Unfortunately, I thought it was a spiffy idea to wipe it before giving it to her... only to realize one of the key apps she needs (Kindle) is only for iOS 6 now... we have it on the iPad before.... but now, I can't re-download it... Does anyone know where I can get a copy of the older version of this (and maybe other?) apps?? There has to be an archive online somewhere... right? Thanks in advance for your help!
