Sean Kovacs, the developer of GV Mobile, seems to have submitted his app for approval to the App Store. Here's some information about the app:
"The GV Mobile is now called "GV Mobile +". The app has a new icon, and the app will support retina display. The app will do iOS 4 quick-app-switching/multitasking. There may be some sort of push notification feature in this release or in a future update. It'll be free for the first 12 hours then will go to $2.99."
