Can I install Communicator Mobile (2007 release) on my device’s storage card?
No. Installing Communicator Mobile (2007 release) on a storage card is not supported because a device does not necessarily immediately detect a storage card when the device starts. As a result, Communicator Mobile’s auto-start feature cannot function as intended. Installing Communicator Mobile to a storage card is also not supported because when a device’s battery is low, the operating system stops running programs that are installed on the device’s storage card.
