I remember reading about a handheld version of backtrack possibility and i am very new to linux and even newer to PDA's

How can i shift from the preinstalled windows mobile 2003 to a linux distro? if it is only by SD card then my options are quite limited as i will be utilising the following wireless card

The device in question is an ACER n30 Pocket-PC.

As it has no navigational wheel i was wondering if that would make it a nightmare for pocket distro's

Any advice and or pointers are much appreciated.

I know this is not a linux distro selection forum but i would like to running a handheld pentesting suite - mainly as it has no ethernet access it would have to connected via wireless - hence the card choice [ its the only one i could find that was b/g compatable]
