Hi Rick

I use GPRS with a Ericsson R520m via Sunrise (which is 7.50 / MB instead of 
19.- / MB @ swisscom).
It was a bit tricky to configure the mobile as sunrise did not support if 
officially (although they sold it with the argument of being GPRS capable) 
a few months ago.

When a GPRS Session is established, it is very stable.
I did use it quite often on the train in between St.Gallen and Z�rich. It 
keeps the same IP and the connection open during all the coverage holes or 
parts with only swisscom coverage. Of course you don't get or send any data 
until you are out of the holes.
But Linux which is very tolerant about very long TCP delay's mostly kept 
ssh and irc sessions open and had no problems to continue at the place 
where it was before the signal dropped.

The only problem I have, but I think it's a firmware problem is, after 
every connect I have to 'reboot' my phone to be able to make make a new 
connect.

Some things I found out about linux and R512m via irda:

- Disable Hardware Handshake on the serial IR port (/dev/ircomm0) and use 
only software handshake.
- You don't get the 'remote' IP, so just use a dummy Private IP as remote 
IP. Set a default route to the address you got as local ppp interface address.
- Sunrise does NAT. So only outgoing connections work (but I think this is 
good so, else everyone could ping you with very expensive packets :-)

So I'm quite happy with the way sunrise GPRS works. Of course, it's very 
cheap for ssh, telnet or irc, but as soon as you want to surf the web or 
read emails, it's probably cheaper to use GSM Data.
