UPDATE 2: Wow. This app sucks. Kill it, it restarts. Kill it, it restarts. Kill it, it restarts. Repeat ∞. Uninstalled.
UPDATE: While the app seems to work fine, similar to a number of US users, we have also found that this app launches itself often, for apparently no reason. Version 1.0.0. You will definitely need a task killer for this one.
A reliable source has posted the apk for the Photoshop.com android application that is only available in the US. md5sum for the apk we downloaded is c8c7c4b8798472199d3116dbb6639f77
