Embodiments include methods, server systems, and computer-readable media that provide manufacturer-independent interface to mobile computers via a plurality of mobile communication devices. These embodiments associate a particular service account with a first mobile computer and with first and second mobile communication devices, and transmit to the first and second mobile communication devices a first download list identifying files to be transferred to a first storage device associated with the first mobile computer. Embodiments also receive from the first mobile communication device a first remove list identifying files transferred by the first mobile communication device to the first storage device. Embodiments also delete files identified on the first remove list from the portion of the data storage associated with the particular service account, create a second download list comprising the first download list but not the first remove list, and transmit to the second mobile communication device the second download list.
