Phone is rooted
Usig QPST, mode is simple IP (Check the all things root guide for boosting 3g)
updated /system/build.prop as mentioned above
installed wifi_tether_v3_1-beta14.apk (You can find it ;-) )
Adding this post on my computer via wifi tethering now.
Very cool, thanks for all of your help!
BTW, I don't know if the Simple IP setting is necessary, I did that trying to boost my terrible bandwidth rates.
