Application Download Sample doesn't work in Remote mode

No - I eventually gave up on Remote Mode completely because of the many such problems that it causes.

eg, Error on sending sms (again) - #2 by awneil
also timer durations incorrect, etc…

You mean GPRS, of course…?

But DOTA over GPRS is not the same at all; you would not be using XMODEM over a GPRS (TCP/IP) link - would you?!
