2.2 Froyo Kills PdaNet
I used Pdanet flawlessly for months, took my HTC Desire in for a "checkup" at CSpire store to see why it wasn't getting good signal when roaming, and rep uploaded the newest operating system (2.2) for me. Killed my pdanet immediately. Program would open as usual, show "on and running", but phone would immediately shut down the "Mobile Network" when pdaNet was turned on.
Some months later I bought a second HTC Desire to replace my screen-cracked one, and it was still running 2.1. Now, again, pdaNet works fine. I just can't upgrade the operating system. Fine by me...
