Which version ISILO to download and buy

[hopp@iinet.net.au]

Does anyone know what form of ISILO I should download for my spanking net Xda Atom with Windows mobile 5.0 I have tried smartphone and "pocket", neither of which seem to work. It is the free trial version so I am reluctant to purchase the formal versionVery frustrating.
HELP

[iSilo]

The XDA Atom is a Pocket PC device, so you would install "iSilo for Pocket PC".
