facing sms/call crashes with teh iphone after i changed sim cards.
Previously, my chineseSim was working fine in Singapore.
But when i brought the phone to Australia and using an Optus line.
I am unable to make calls as it will immediately take me back to the home menu.
I have tried switching the country to Australia via iWorld but it did not help.
Hoping to get some advice from you guys/gals.
thanks in advance....
