Many are suffering from the wifi tethering problem and are unable to turn their spica into a hotspot! Users have changed from yonip to horsepower kernel but of no use!!
However, to my surprise this is a theme related problem and not a kernel-related. I have just changed my theme and it seems to work again. The theme is the default Mod-X theme with a little bit of modification in the battery icons!!
PS: Those suffering from market install problem, shift to Mod-X. It may or may not work, but its working for me!! CREDITS: Voku!
