I am getting Error 628 when I try to connect to the internet when my Pearl is tethered to my laptop. Also, does AT&T charge extra to use the Pearl in this manner and if so which service plan do I need and is it worth it, since AT&T seems to nickle and dime for every feature that is included with TMO?

Thanks!

AT&T does charge extra, however there is a way around it.

Follow the directions in this thread:
[User] HOWTO: Use BlackBerry As Modem For Laptop!

Use the Cingular Orange settings - except change +cgdcont=1,"IP","ISP.CINGULAR" to
+cgdcont=1,"IP","WAP.CINGULAR"

I have been using it this way for about 2 years now and have never been charged extra nor did I need to get the extra tethering plan.

What about the login username and password?

I used the provided login credentials for Cingular Oragne

I tried this setup and it works great using the Cingular provided information. On my laptop is shows a connection using the modem, but for some reason I cannot browse the Internet. Any ideas? I normally using my wireless network connection but when I am on the road, this would be great. Not sure if I need to enter DNS settings someplace.
