I'm glad to hear that my step-by-step instructions worked for you.
With RebornROM I use Quick Settings
(by Halfbit) to launch WiFi Hotspot. It works perfectly with the old version of Quick Settings that I'm using. I don't know if that feature is still part of the newer versions of Quick Settings. From within Quick Settings, you may have to hit the "settings" button, hit "Customize", and then drag WiFi Hotspot up from the hidden features. Quick Settings is also nice to have on your homescreen to quickly access setings like WiFi, 3G, flashlight mode, etc.
I guess that FoxFi would also work. If you use your PC's web browser to go to the Google Play Store for FoxFi
you'll see in their product description that Sprint won't allow customers to download FoxFi from the Play Store anymore. However, the developer provides instructions for downloading FoxFi directly from their website at the following link.
