Hi,
I've installed the AntiTheft Beta on my HTC Desire and every reboot brings up the 'This phone is lost or stolen' dialog with a request for the unlock PIN. I've unlocked it and marked it as found several times on both the website and by SMS but to no avail.
I just rebooted it at 09:44BST today (IMEI ends in 9127) if there is someway you can check what is going on.
Ta.
