I'm not quite sure where to post this but I just got a message from my Foxfi app that I needed to upgrade to Pdanet+.
In doing so they are running a promotion that you can upgrade to the full version for free if you have ever purchase the full Pdanet or Foxfi apps. Just so you know.
All you need is the serial number and email that you originally purchased with.
