Here are instructions to listen to Michigan Football on your iPhone, iPad, or Android device. It should be good for the 2013-14 season. At this very moment I am listening to Michigan play against Notre Dame.

iHeartRadio

• Get the iHeartRadio app. It is available for both iOS and Android.
• Tap the “Live Stations” tab

• Scroll down through the states to the Michigan section and look for these stations:

Michigan —> Ann Arbor —> W4 Country 102.9
Michigan —> Grand Rapids —> WBBL 107.3

The station descriptions may say that a song is playing but the stations should actually be broadcasting the live radio broadcast with Jim Brandstatter and Frank Beckman.
