College students are tradtionally early adapters. If an indication of the future - it's good news for the mobile ad industry. A new survey from Ball State University from 2005-2007 found that 56.3% of survey respondents would accept ads on their mobile devices if they were to get something free in return. Some other findings:

• 37.4% of college students said it would only take the offer of a free ring tone for them to accept advertisements on their cell phones.
• 21.4% preferred a discount or coupon to a restaurant, movie or grocery store.
• 20% wanted free minutes, upgrades and access to the Internet or music.

Students are becoming less worried about who has their information. Those that were "very concerned" dropped 25% between 2005 and 2007.
