LONG story made short, i'm off the PDA/PPC and back to using the LG voyager, with the $15 vpak, and DUN is alive and well, i'm posting from my laptop with the voyager & DUN right now, so for me with the NationWide plan the $15 Vpak DUN is still working here in So Calif.
I really like the HTC TOUCH/xv6900 Pocket PC, and the internet connection was much faster, but i was having problems making calls from one area, verizon would give 'authentication ' error msg when trying to call out, incoming calls worked, internet worked, but i couldn't call out from this one area, really strange
I tried to fix the issue by updating the FW, and ended up with a $400 paper weight, i'll keep trying to fix it, but for the time being i'm back on my Voyager 'dumb phone' as they say on HOFO
