Mit Hilfe des USB-Kabels lässt sich der interne Speicher des Touch’ nutzen; Internetzugang sollte über Bluetooth mit Hilfe von PAN funktionieren. Ich bin aber noch nicht dazu gekommen, das zu testen.
Die Synchronisation zwischen PDA und Notebook dürfte mit SyncCE funktionieren. Auch dies habe ich noch nicht getestet.

PAN wird übrigens in einer der nächsten Versionen des NetworkManagers integriert werden. Es existiert zwar bereits ein Patch, der libbluez ansteuert. Der Patch ist allerdings gegen die Revision 2574 von NM programmiert worden.
Momentan ist aktuell die Revision 4xxx. Ich hab’ vorgestern versucht, den Patch auf den aktuellen NM-Trunk upzudaten – leider ohne Erfolg und zugegebenermaßen auch mit wenig Lust. War eine stupide Arbeit, beide Forks mit dem Patch abzugleichen.

Die Jungs von Launchpad diskutieren die Integration von PAN in NM hier. Im NetworkManager-Tracker ist der PAN-Request hier zu finden, inkl. des veralteten Patches.

Edith: Ich bin eeeUser-Forum über einen Thread gestolpert, in dem ein kleines Python-PAN-Script vorgestellt wird.

Hier der Code:

Good job!

Ich hab es auf meinem Touch ausprobiert und es funktioniert einwandfrei. Wichtig: Das Script als root starten. Auf dem Touch muss unter Programme -> Internet Freigabe bei PC-Verbindung “Bluetooth-PAN” ausgewählt und danach das Handy mit dem Notebook gepairt werden.
Ich bin mal wieder von Linux begeistert. Und von meinem neuen Handy auch
