EA’s college football franchise NCAA Football arrives in the App Store today in two different flavors: NCAA Football ($6.99) for the iPhone and iPod Touch, and an enhanced NCAA Football HD ($7.99) specifically tailored for the iPhone 4.

The iPhone 4-optimized version of NCAA Football boasts high-resolution graphics suited for the device’s Retina display, eliminating many of the graphical flaws that would be apparent with pixel doubling.

Both versions of the game feature 55 collegiate teams, a season-long single-player mode that simulates all major Bowl games, a fully-featured Team Editor (allowing players to customize everything from jersey colors to fight songs selected from an iTunes playlist), and a multiplayer mode playable over a Bluetooth connection.
