Last week Telltale reported on the release of a visual upgrade for the iPhone version of Tales of Monkey Island. The update is available to those who own the "Retina" capable iPhone 4 and 4S models, and the difference is like Wally B. Feed with and without a lighthouse lens.
The upgrade is free to those who can make use of it, and there's apparently some sort of discount going on with the series at the App Store right now, so, you know, food for thought for your nonexistent people who have an iPhone, read this site and never played Tales of Monkey Island.
