Gamefly released an app for the iPhone this week that could quickly become your go-to place for game info. The application is free, and integrates easily with subscribers accounts. You can manage your account as you would expect, and select games for rental on the go, but the app has a lot more than just account management.

The Gamefly app is full of game info, including control lists, walkthroughs for some games, cheats for others, user reviews, and achievement lists. You can get news feeds from ShackNews, which Gamefly picked up earlier this year.

Gamefly co-founder Sean Spector wants the app to be everything for every gamer, not just Gamefly subscribers. He mentioned plans to expand the list of titles in the app and even wants to add more news sources and reviews. I’m guessing he wouldn’t mind if the thing boosted subscription rates along the way.
