Wifi apps on rooted phones??

http://forums.androidcentral.com – Okay. I need a free app to turn my phone into a wifi hotspot. Sounds easy?? My Vibrant is running Android 2.1 so I don't have Google play, and my phone doesn't actually work through a company. I just use it on a wifi signal. My phone reaches the community wifi but my laptop doesn't! :/ (HowTos)
