Twin Paradox SolarExpress PDA

So I've really been wanting one of these to connect my N400 with SprintPCS Vision service to my Z so that I can finally browse the web and listen to internet radio wirelessly, anywhere. The annoying thing is that Twin Paradox has delayed to release of the SolarExpress PDA repeatedly until the following month for months now, putting it perpetulally out of reach since I first saw it. The most annoying thing: I wouldn't need this if Sprint would finally just allow their customers to use bluetooth phones on their unlimited wireless web service. Instead I have to cobble together a bunch of devices to do the same thing.
