According to winrumors a WP developer Julien Schapman is planning to release WP7 device manager that includes a new way to jailbreak Windows Phone 7 devices.Schapman is expected to release his Device Manager application after Microsoft release its first Windows Phone 7 update, ensuring that the exploit is not closed in the process.
Schapman spells it out in an email to Winrumors:
“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 is not ready to mention more details about the application as he fears that Microsoft may patch the vulnerability. On the side not Geohot has also shown interest in developing Windows Phone 7 jailbreak tool and he was greeted with a free WP7 by Microsoft.
