Ain't happenin'. The problem is that the USB port on your PDA, and most
current ones, is a client port. USB comes in host (like on a PC) and client
flavors, like most peripherals. While you can make a cable for Host to Host
communication, to connect two PCs together to transfer files for instance,
you can't make a client talk to a client. Keyboards, mice, etc, are clients.
Your only option is BT. Never seen an old handheld option to use it as a
display for a PPC or Smartphone, though there have been a couple of new
devices that do just that announced, but not released. They also were
suggesting around $500 for SRP. Comments put that as a bit steep.
Unfortunately the current crop of WM devices also don't have serial inputs,
other than over a BT serial profile. Back in the WM2003SE days, and before,
many devices actually had RS232 capability at the docking port. Direct
connect keyboards were available back then.
BTW, where did you find a Windows enabled iPhone ;)
