Do BIS data plans affect the capibility of an blackberry being BIS or BES? For instance, if a blackberry has BIS data plans, will it be able to sync to outlook and get the coporate emails? And what about the vice versa, if a blackberry only has BES data plans, can it be synced to both types emails accounts?
A BIS plan will not be able to activate on a BES. A BES plan will activate on a BES and BIS will be available (if the corporate IT policies will allow it.)
