Now you can see your friends contacts in iphone even if the iphone is under password protection. Let you explain this Security Flaw;
You can try it but before set your iphone to this condition:
1:Make your iPhone use pass code lock.
2:Have your contacts marked as Favorites with links,addresses,phone numbers and so on in address book entry.
Now you can try;
1:When you see the pass code entry screen, tap "emergency call" from keypad.
2:Tap two times on home button.
3:Now if you tap blue arrow next to contact name.
Now You will get full access to the iphones applications like safari, sms, GPS, contact lists. Really a big security flaw for business people. I think many people have reported about this security flaw to Apple. So, Apple will fix this soon.
