Is there a way to enable WiFi-tethering without root access? Is there a way for WiFi-tethering without root access.

I mean before Froyo.

I have HTC Hero 2.1, and frankly, I don't want to root it for security reasons.
I don't know of any way to do wifi tethering without root (before 2.2).  You can, however, use bluetooth or a USB cable with PDANet which does not require root.
