Well after a few hours of searching online, I actually found a protective case with visible plastic on both sides at letstalk.com. They seem to be the only site that has allot of accessories for the Upstage II.

Hello everyone, me and my fiance just purchased two of the Upstage II phones but we haven't been able to find any protective cases for the phone. Can anyone direct to a site or place I may purchase one from? Thank you
