I have a bluetooth adapter for my PC. Internet connection sharing turned on with a generic 192.168.0.1 assigned to my bluetooth adapter TCP settings. Can the bluetooth adapter on my PC act as a gateway for the blackberry? For instance, does the blackberry have a configurable TCP stack or something once i sync with a device ?

And is there something third party that could help me with this ?

sorry. I have a 7100, not 7100t

one more apology

T-Mobile BlackBerry 7105t is what i actually have now that i am looking at blackberry's site.

No. You can not use the BT on the BlackBerry for Internet access.
BT on a BlackBerry is extremely limited.

I have a 7105t as well and I spoke to a t-mobile reptoday and he saysthat the only thing the bluetooth radioisgood foris hands free. That is the only thing you can use the bluetooth for.
