I used to have a PDA phone with Pocket PC until it was stolen. I set up mine with pop3 so that it goes directly to my office mail server and checks e-mails, but leaving a copy on the server. I only checked e-mails when I told it to and I limited it to 2kb. If I wanted to see the whole e-mail I then downloaded that particular e-mail completely. I had to do it this way otherwise the tons of spam would have killed me in charges.
Sounds like a good set up. I use a pop3 account also. I was using their MyMail Desktop Assistant to push email to the PDA, but I can see how that would eat up my quota.
Data transfer in the US is a killer. Avoid as much as possible. Yes there are roaming charges for data transfer in the US and there is really no plan that covers it.
Dang, they never said anything about that. Now that I understand it better, I see why there are roaming charges. I might switch from their Canada One Rate plan to their Digital One Rate plan... that should take care of the roaming charges, up to the quota at least. It seems I am traveling to the U.S. on business ever more frequently.
You also have to be careful if your phone has a GPS, it goes towards data transfer big time, especially in the US.
Yes, I have the iPaq 6515 with GPS.
This doesn't make sense -- there shouldn't be any use of the phone's GSM/GPRS to access the GPS. Normal GPS receivers don't, nor do GPS cards for PDAs, so I can't imagine a built in GPS would be that way. It's not like I'm using IE on the PDA to provide the mapping; I downloaded Pocket Streets.
