I created an updated teams.dat file for the 2012 season with the correct team names and a logo pack you can use with it. Just use iPhone Explorer (now called iExplorer) to do the following. If you have trouble getting it to run, run it in administrator by right clicking on the program and clicking run as admin.
Download the two files below.

Simply overwrite the 2012.tar zip file with the attached updated file. Put it here.
Apps/com.ootpdevelopments.iootp2012
And put the logos in Apps/com.ootpdevelopments.iootp2012/iOOTP2012.app/iOOTPData/logos.
Having trouble? Just watch my 2 minute video on how to do it below.

The logos are taken directly out of the 2011 iOOTP section and the only ones I messed with are the Tigers, Dodgers and Marlins, Astros and Diamondbacks. In those cases I fixed them to make them look better in iOOTP 12.
Enjoy
