dumb question - do we delete all existing "lbs" files from the 4.5 java folder? or just copy over the files from 4.2 and overright some?
2. BB Maps. The issue is that the version of BB maps that comes with 4.5 requires a service book, which at&t refuses to push down (or, more accurately, pushes down blank service books). The solution, of course, is to load an older version of BB Maps. Replace the LBS.alx file with the file from a 4.2 installation and copy all of the modules (cod files) with "lbs" in them from the 4.2 installation to the 4.5 java folder. Then run app manager.
