HELP! Whenever I tap on a search field on any type of field that requires bringing the keyboard up, the iphone blinks and goes straight to the homescreen. EXAMPLE: it takes you to the homescreen when: you tap on google search, web address, notes, contacts search, app store search, and everything else that requires typing! PLEASE HELP! AND ALSO WHEN YOU SLIDE TO SPOTLIGHT SEARCH IT RESPRINGS

Something you installed from Cydia is not supported on your iPhone iOS. Or it has a bug. I would recommend uninstalling your last package and respringing and seeing if the problem is fixed.
