I have used Siemens MC35iT which is a basic RS232-attached GPRS modem. It works fine with Linux pppd. Config is attached below. That particular unit is GSM900/1800 only, but they have other modules which do 850 and 1900MHz: http://www.tdc.co.uk/index.php?key=gprs&nav=gsm TC65T looks like it would do the trick. Of course for unattended operation it's up to you to ensure your pppd config will redial automatically if the line drops, and that you have scripts to bring up a tunnel automatically if you need one, etc. However it won't be as neat as a USB or Mini-PCI solution as it's a separate small box and needs a power supply.
