My girlfriend has a 3 year-old iTouch running the most up to date software it can- 4.something. She tried to download the Kindle app, but a message popped up and said she needs to have iOS5. How can she get the last version of the Kindle app that is compatible with her Touch? I understand that developers can't be expected to keep updating apps for old equipment, but 3 years isn't exactly ancient. My MacBook is going on five years old, and I can still download Safari and other applications that work on it, even if they're not the newest versions. Please tell me there's a way to get older versions of apps for older iOS!
