This one is on apple – Birthday Sweet - Birthday calendar & reminder for Facebook Review

Apple needs to warn users when an iOS release is not backward compatible with a class of apps. The warning would give us time to copy out the data before upgrading. Failing that, now release some kind of software to rescue the data that was being maintained by 32 bit apps that will never be upgraded. This is apparently abandonware and we have no way to retrieve data we counted on Apple to secure. The biggest problem is that they don’t even see the need to rectify this. I am afraid that this company’s competence died with its founder.
