If I Try TextExpander for iPhone & iPad Version 4 and Later, What Happens to My Snippets?
How to ensure your snippets remain the same between versions
The first time you launch TextExpander 4 for iPhone and iPad it will either merge your Snippets from your older version of TextExpander with what is in your TextExpander account or what is in your TextExpander account will override your local Snippets.
We recommend you do *not* keep both versions of TextExpander installed on your device at the same time. But, TextExpander 4 for iPhone and iPad stores its local data in a different file, so if you install the older version of TextExpander touch, all your Snippets will remain as they were.
