I spent a few days trying to get 4smartphone to work for delivering my POP3 e-mail to my Treo. I could not get it to peacefully coexist with Activesync (for file syncing), so I dropped and reverted back to plain old Activesync.

However, now I can't get the device to sync using the normal RNDIS USB connection. I finally tried the subswitch utility and that solved the problem, but I still don't understand why the RNDIS connection suddenly wouldn't work.

Any ideas or suggestions?
