Default New Shift from 1saleaday

I just received my HTC Shift from 1saleaday. It has an Italian Rom on the WM side and I do not have a working sim card, since I switched from ATT to Sprint a few years ago for my cell service. I have read a lot of the threads and cannot find a way to Liberate the WM side without the working sim card. Are there any solutions for people in my situation?
