to all the sifu's, perhaps this is a common issue but would love to be reassured that there is nothing wrong with my iphone. hahaha

the other day, while taking pics, my iphone hanged. so i guess its normal?

also, i notice, the phone gets laggy after awhile... after deleting my sms's... it gets better. but my problem is, i only store like.. 10 or so sms... and that makes the phone lag?
