App for locking the iPhone via sms?
since the iPhone can be operated also w/o a sim card, I defined a lock-code which has to be entered each time the iPhone recovers from sleep.
My previous mobile phone was a Nokia E71, which allowed to put the mobile phone into lock-code protected mode by sending it an sms with a predefined text. This can be very useful if the iPhone is stolen, or just being forgotten in a public place.
Is there any app available to enable the iPhone do the same?
Thanks,
