I emailed the guy there.... Problem is, previous sim adapters haven't been great. Turbosim and Yessim have both had success, but been sketchy at best. Many reports of them only working as little only a couple days before packing up and refusing to connect to service

So buying an iPhone for hundreds and hundreds (these fucking things sell for between £300 and £600, sometimes more ) for it to only work for even a few months makes for a fucking expensive iPod Touch
