Same problem here.. I need to download the generic client but the link is dead.
I am using Samsung i780 (run on WinMobile 6.1) and Sony Ericsson Z250i, both phones are not able to use Form.
On i780 I succeed to install the form client but not able to receive any form sent by FrontlineSMS server).
On SE Z250i, not able to install the form client.
