iPhone in built spotlight search is some thing which is least used by users, So many user may just want to remove it as they don’t use so don’t want to get annoyed by seeing it while browsing through several home screens in iphone.
NoSpot is a free app released on cydia under bigboss repository. It completely removes spotlight search on your iphone. This is great for those who have an iphone 3G and are stuck with that very slow iOS 4 performance. You can search on cydia with its name.
Removing spotlight from your iPhone help you solve the lag issues and also make it run smoother and load up quicker. Until Apple comes out with an official fix for the speed at which the iphone 3g handles iOS4, this is a great workaround.
