Delete an important text? Need to get it back? Undelete SMS scrapes your SMS database or Spotlight history for deleted records and recovers them! Displayed in plain text, you can copy the texts you want and stick them in a note, email, etc.
Note: Undelete SMS is a forensic recovery tool, and is not guaranteed to recover all or any deleted content. Undelete SMS analyzes remnant deleted data that has not yet been overwritten by new data. While Undelete SMS can often produce useful results from an actively used phone, or backup restored from an actively used phone, it will not produce results on a freshly restored phone without a backup. Depending on user behavior, Undelete SMS may retrieve varying levels of data, including possibly no data. Undelete SMS is a utility, and not a guarantee.
Undelete SMS costs $6.99 and can be found in the Cydia Store.
