I cannot even describe to you the overwhelming feeling of accomplishment that I have now that I have finally tethered my Blackberry Curve (Alltel) to BOTH my laptops. On Windows 7, it was fairly simple: pair the phone, then set up a com port. On the Mac, is was pair the device, set up the DUN for Generic & CDMA. After that, the phone number, user name, and password are: #777, <your 10 digit phone number>, alltel.
It took me over a year to find that information on the internet. I don’t know if people just don’t use Alltel or what, but it was exceedingly hard to find.
Down speeds are around 280kb/s, with uploads coming it at about 90kb/s. Latency is around 330ms. Not great, but not bad either. I can easily work on those speeds, so long as I don’t need to do any heavy uploading/downloading.
If you need help tethering, leave a comment and I’ll see if I can help.
