Fantastic idea, and maybe it's my device (Samsung Galaxy phone, Galaxy Tablet, both running 2.2), but...
this is not working for me. I have unlimited uncapped data on my phone and want to tether my tablet to my phone, and it's connecting to a clickwall access point that I *do not want* to connect to, no matter how many times I remove it.
A previous user had to uninstall and reinstall it, but when I tried that, it won't let me because my purchase was refunded (and the market hasn't caught up to that yet).
FANTASTIC idea...implementation needs a little bit of polishing.
