Ziphone?? melalut jauh dah brother.... apps kicking back to spring board is not a u/jb problem.... its the apps itself... for other 3rd party apps that behave d same, all we did is reinstall them back... but this is a default iphone apps. What about resetting ur iphone? some fellas called it hard reset but my terms of hard reset is restore for iphone... dont get confused... lets say restart and see if problem persist...

@ d3vilzzzz...

Maybe accidently duplicated via sync ah?.... i had d same prob (not a big deal lah) before... i created a gmail acc in iphone and DL all folders and messages via wifi.... then my outlook also have have d same gmail acc but not fully configure (Still cant receive mail from outlook)... So when i sync with d mail thicked, all of d sudden, my iphone have 2 same gmail acc heheheheeee....

So, in order to prevent this, what i did was, i quickly fully configured my gmail on outlook and get them to receive and send mail successfully... delete my gmail acc from iphone and sync back outlook gmail to iphone... from there on, no more duplicated acc everytime i sync...
