sure, i own an ipaq 3660 (wich is the same as 3630 but with 64mb main-mem, as u know). my nic is an elsa mc-11 wep64 (wich is an orinoco silver) with the lucent 8.10 firmware branded. ministumbler works fine for me (thanx again to marius for his work). you should use some other handy tools also to infiltrate the target(like ceniffer, vxutil and tolls from interrorem). this makes your ipaq a wireless hack-in-the-box-toy.

have fun
