To everyone asking for a cab2oem, why not do SDConfig.txt? Load up all the .cabs onto your SD card and make a file called SDConfig.txt in the root of your SD card with the following:
LOCK:Enabled
CAB: \Storage Card\cabfolder\application1.cab
CAB: \Storage Card\cabfolder\application2.cab
CAB: \Storage Card\cabfolder\application3....cab
LOCK

RST: Reset
