I was able to get Foxfi to work a bit on Jelly Bean and Verizon Nexus Galaxy using a Bluetooth network connection. My notebook has built-in Bluetooth. If you don't have Bluetooth, you may be able to buy a USB Bluetooth adapter cheap.
In Foxfi, you can enable Bluetooth if you click on the Foxfi Bluetooth button. You should click on the Bluetooth help button in Foxfi to get detailed instructions on how to set it up on you OS.
I was able to connect to the Internet, but I was only getting a little over 1mb when I used to get between 15-20mb with Wifi. I only used it for a few minutes last night and found it a little glitchy. I'm hoping Foxfi will be able to fix this.
Finally (off-topic), I also noticed that IRIS is also not working properly on Jelly Bean on the Nexus Galaxy.
I have Samsung Galaxy S 3 with jellybean 4.1.1. I was not able to run Foxfi87 . somewhere it is said it is not compatible with JB. I downloaded PORTABLE WIFI HOTSPOT WIDGET BY 'taiseiko' from google playstore . Now foxfi87 runs fine . How I dont know.....
