I pair my Motorola Razr through Cingular & Axim x50v with no problem. My daughter has a x51 & has no problem with pairing with her cell phone; we have unlimited data plan; no extra cost with provider. Using this now while writing this reply.
It is the same thing. T-Zones is what you want. I updated my instructions to include the proxy setting. I forgot to add that. I have no problem pairing my little Razr and getting e-mail and internet. I would like a one button connection. I need to make a sScript or a mortscript for this and then life will be bliss.
You need to soft reset each time you want to change your network settings for internet browsing. This is not an issue with checking email (I do not know why). For example, if your settings are "My Work Network" for wifi browsing then you will have to change the settings to "Blutooth Work Network" and soft reset to brows with your phone modem. Then if you want to switch back to wifi you need to change the settings back to "My Work Network" and soft reset. This bugs me but it is what must be done. Lots of button pushes each time for this unless you make a macro for it.
