Adobe has updated Photoshop Express for Apple iOS to version 2.0.  The update includes the ability to purchase an in-app camera pack that leverages powerful noise reduction based on the outstanding tech in Lightroom 3 and CS5.  Additionally, the $3.99 camera pack offers a self-timer shutter trigger and an auto-review option.

You can find Photoshop Express 2.0 in the Apple App Store – and it’s still free.  If you want the extra horsepower of the above features though, you’ll have to spring for the $3.99 Adobe Camera Pack as a purchase within the Photoshop Express App.
