This is really as simple as looping through each record in an Ajax store and adding them into a localStorage store, and vice versa. The problem is, that right now in PR2, localStorage is broken.

That's a shame. I'm busy developing an app using Sencha Touch (1.10) but as I'm still busy coding away I've migrated to PR2. Does anyone know the ETA on the localStorage solution for PR2. When is PR2 due for official release?
