Apple notification system is in debate since its inception at the time of Appstore launch but over past few years this notification system needs major redesigning which is on the way in iOS 5. Apple shows updates in the form of numbers on the top of Springboard icons e.g. if there are 29 updates in Appstore you will be displayed 29 on the top of Appstore icon as displayed in snap below. In the meantime if you are annoyed having numbers showing up on AppStore, Mail, SMS, Facebook etc then BadgeClear is the solution.
BadgeClear is a Cydia Jailbreak tweak which allows you to remove these notification badges. So simply visit Cydia and install BadgeClear using procedure here. When you have installed BadgeClear you simply have to keep the icon on the homescreen pressed so that they start jiggling. Now simply click the annoying badge and its removed. Simple.
BadgeClear cost 0.99 US$ so if you like the app purchase it from Cydia.
In order to enjoy such tweaks you need to Jailbreak so you might like to see Redsn0w Jailbreak & JailbreakMe or to Jailbreak while preserving your baseband (software unlock) see TinyUmbrella, SnowBreeze & PwnageTool, .
