AGPS data upload is in the process of development in BT747 for 2.X versions.
I do not have such a device, but Dirk Haase has been very helpfull in providing me with transcripts of the beta version results.
You may want to try it and provide some feedback too. I am particularly interested in how the J2ME version works.
These developments can be downloaded in the developement download section on the sourceforge site.
