What I did was downloaded the .zip file to the desktop, and extracted the .cab file to my SD card. Then I put the SD card in my phone, go to 'file explorer' under programs and move the source from 'phone' to 'card'. The .cab files show up and you simply tap whatever you want and your all good.
Remember once it is installed to do a reset on the device (push stylus into reset hole on back of phone under battery cover).
