CPT v3.0.3 has just been posted in the App Store. This version only addresses a couple of bugs, so if you are not affected by these, then you can choose to wait for the next upgrade before updating.
Those running CPT on iPod Touch devices, particularly if running iOS 4.2.1, are urged to apply the upgrade as this version addresses a problem some of those users were seeing with the Pain Location Mapping Tracker tool. Also, if you utilize the CSV export functionality, we have a minor fix for you as well.
Check it out. It should be available in the App Store now.
