So far I've only tried two ways of net through my blackberry, the usb/quicklink method and the bluetooth adapter/software method.

Speeds are the same either way...I average 2-3 bars 1X at home, so I'm not going anywhere near fast enough to hit any down/up limits with either method. At this point it's purely just a matter of preference.

As for thackstonns's method...I got lost trying to follow those steps, would need more details. Also...would that have any effect at all upon my actual net speeds? Or would it just simply be another option of connecting to the net?

From the looks of it...the only way I can better my net speed is if I were to get better reception. I've looked in to the possibilities with this...and it seems like "reception boosters" tend to cost $400+. It would be nice to figure out some easy/cheap way of boosting signal, even if it's just a little bit more. Anything would be better than a 130kbps down bandwidth/16kbps actual download rate.
