The power of drellisdee is strong. His effort has brought a custom kernel with ext and android-wifi-tether. The link is not public on the android-wifi-tether google code page so don't look there yet. Link: http://android-wifi-tether.googlecode.com/files/wireless_tether_2_0_5-pre9.apk Please test by getting drellisdee's kernel and the unreleased tether app. Notes: The kernel needs rom support for app2sd to work with drellisdee's kernel. This is better then barnacle because it supports more devices and is open source.
