I was able to get Fofi working over Bluetooth on my Sprint S3 coupled with pdanet running on my Xoom tablet. But with the S3 on 3G it was a slow connection.

I still can not get FoxFi to work on my Sprint S3. Any suggestions? My laptop with Win7 says it can not connect.
Are you using v. 1.91.3 ? Try switching your phone to wifi, and attempt to start the foxfi. It may or may not work. Then switch your phone to 3G/4G, and start up the foxfi app again. Sometimes I have to start it twice for it to work.

Just got s3 on sprint, got pdanet working for usb tethering, but need wifi tethering as well. i installed foxfi, and it does broadcast, but i cant connect to it with either my pc or other phone.
anyone having success with this? any suggestions for getting this done without rooting?
I don't know how anybody gets Foxfi or PDAnet to work on a Sprint Samsung S3. The software is BLOCKED by Sprint. Even Google Play says it is not compatible.
yes i know it was blocked from the store. thanks for the link, that's the one i used to install. i would think that the app would work, seeing how the makers are making it specifically available for sprint users like they are.
anyone having success with foxfi or any similar app on sprint?
