Our BB devices in our BES enviroment (large gaming company) have policies that lock the devices and prevent some apps from being download/installed. Pretty much mirrors similiar desktop policies (what can/can not be installed on a company laptop or desktop). However, the other driver for the 3rd party apps is cost of data plan. We have found that 90% of our user base on our BES environment only use about 8Mb of data or less. This was a huge cost saving opportunity, in that we reduced 80 to 90% of our users to a tiered data plan, saving about $20K a month in BB data plan fees (~1600 users, reduced $15 month from unlimted to some corp liable plan that was tiered, saved ~$24K a month). Almost $300K a year!!!! I asked for my bonus back as we saved to company some good coin -- you can figure the answer I got...
