Seems I deleted an app or a directory too much from my Android 2.3 phone. In particular I remember removing an app called App2SD or similar. Now, after booting the phone, I cannot see the apps anymore that were installed on the MicroSD card. However, I would like to access data from one app in particular. This app is called Epistle, and I was thinking about simply reinstalling it. However, it is not available on the Play store anymore.
What strategy can I use to get access to the data of that app?
