A T-Mobile G1 is a very linux-friendly phone, it runs it's own version (Android) of Linux. The Asus R2H runs Windows XP by default, but a guide at http://www.xs4all.nl/~sozonko/asus_r2h_howto/ tells you how to install Linux on it. Hope I helped.

Sorry, I replied to the wrong question. That should have been:

A T-Mobile G1 is a very linux-friendly phone, it runs it's own version (Android) of Linux. You can use a service called Funambol to sync your contacts. The list of supported devices is at http://www.funambol.com/solutions/devices.php, and an unofficial (I think) Android client is available at https://android-client.forge.funambol.org/. Sorry for replying to the wrong question earlier.

T-Mobile G1 and successor samsung model ( comes with android 1.5) running android are good linux phones.with good support from google,u can definitely buy it.

The Pc phone suites to try are

3.wammu(frontend for gammu)
4.gnome phone manager

i had success with gnome phone manager and could only send sms from it

There are some android fones available in market now also theres nokia n900 and palm pre

One great thing about the Android phones are that if you have Google Contacts set up, you don't even have to do anything special on the phone. When you start the phone, it will ask for your google account info, and once you enter that it will automatically sync all your google contacts with your phone and keep them current.

You can import contact files from other contact managers into the Google contact interface and have all your contacts in one place, plus auto synced with your phone. It works swell
