I'm not contradicting myself, I said I could dial-up tether.
To clarify, tethering can be done using the dial-up modem part (e.g. using the phone as a dial-up modem at a really slow speed where the telephone part is disabled (meaning I cannot make a telephone call while using dial-up tethering; thus the clarification in the original posting that tethering is via dial-up not 3G).
3G networking and 3G tethering is contractually disabled. BTW, when you tether using 3G, you can use the telephone part; meaning you can tether AND use the phone at the same time, while dial-up you cannot use the phone and modem at the same time.
I am a newbie to cell phones, sorry that I don't know how to better clarify the difference between dial-up modem and 3G.
So back to the original question, does anyone know how to set up the Motorola RAZR V3xx using dial-up to access TomTom Services?
