This post is for anyone that has to deploy blackberry to users in a company and are subscribed to only a blackberry BIS data plan. Typically, you would need to install appworld, then assign a blackberry ID to the berry. If this is a corporate berry, then it will take a lot of time doing this individually. Here you go, from your blackberry browser, click on the link below and install RIMs application – Enterprise Activation.
This can only be done via OTA download and install the app.
