update problems

[samer]

after the update my iris has been acting funny ,camera don't work everytime, i lose my ring tone,can't connect when dialing a number,can't take calls,some apps force close,all that works for awhile then stops working until i shut down my phone and turn it back on then they work for sometime.i had to do that five times in the last two days.even when i get a call the phone dont ring or viprate i only see it on the screen and can't take the call if i tried.
