I'm on a jailbroken iPhone 4 running iOS 4.3.5. There is still not an untethered jailbreak for iOS 5, so I am not able to upgrade yet.
Mint has gotten a bit ahead of themselves and released a new version of their iOS app that requires iOS 5. The old version supported on iOS 4, but it is no longer available. There has been some talk on their support forum about the issue, but there doesn't seem to be a solution.
Where can I find the old version of the Mint app that supports iOS 4?
