My work is switching to the iphone5 but letting us keep our blackberrys for personal use.
How do I just use the bbm? Do I need to have a data plan set up on the blackberry or can I just buy an extra sim card and use the blackberry in WIFI zones or can I get a datashare package with the iphone or will BBM not work at all if there is no sim/data package associated with the blackberry?
