Second jailbreak Windows Phone 7 is on its way. It is expected to arrive soon after first update of WP7 so it will likely jailbreak WP7 SP1 (jailbreak Windows Phone 7 Service Pack 1). Julien Schapman, the WP7 developer, is planning to release a Windows Phone 7 Device Manager that will come with a new way to jailbreak WP7 devices. Here is what he said:
“My unlock method is similar to that of ChevronWP7 in the way they both use a fake registration server, but my method is different and more reliable. For example it automatically detects when a WP7 is plugged in and will check if this is a registered developer phone, if not it will register it once and for all, so the device will never re-lock like with ChevronWP7.”
He didn’t provide any details on the exploit that his tool uses since he doesn’t want Microsoft to fix the hole. Microsoft is expected to release first updated to Windows Phone 7 in February. Julien’s tool may follow shortly.
