hold on, i'm not sure we're on the same page here- i know you can use your data plan and lets say jaiku spot (if i remember the name correctly) to make your cellphone a wlan modem, but that's not what im looking for.
I'm talking about taking the sim card out of your cellular modem and inserting it in your n900 thus achieving an internet connection, but having no cellular telephony (am i making sense here?).
If you're talking about that kind of thing already then thanks..
