Does anyone have experience developing applications on the SK65?

I have a program which runs fine in the simulator, but when I try to install it on the SK65 (I have to use JavaLoader because the Desktop Manager's apploader doesn't work) the device complains that Module net_rim_bbapi_pim is not found.

I can upload the module from the .cod supplied with Blackberry's SDK, but it reports another module missing, and this continues until I encounter a module that's incompatible with the handset.

I'm wondering if the SK65 actually provides programmatic access to its address book - that would explain why it hasn't been loaded onto the handset, and I notice it doesn't support JSR75.

Any help greatly appreciated!
