We mentioned about the Homebrew Device manager by Schapman which was suppose to be released this week. The application not only offers a new way to interact with the phone to load media but also unlocks the phone so one can sideload applications on it.
Since that time, Microsoft and ChevronWP7 have confirmed that the upcoming update will fix the programming error that the jailbreak exploited.
In turn, Schapman is not too keen on releasing his app only to have MS block it a few weeks later so he's doing the "cat and mouse" thing--wait for Microsoft to patch, then make sure his Device Manager works around it. He notes that his app works different than ChevronWP7 but regardless, we don't see any guarantees that he'll still be able to jailbreak the phone himself:
Windows Phone Device Manager release delayed until MS update, as I still haves a lot of cool stuffs to implementation, Also Want to make sure my code will not be broken and my unlock method will pass after the update.
This is all well and good but we're even starting to wonder if waiting for this Device Manager is really worth the hassle and if Schapman, who often promises a lot but tends to under deliver, can really beat Microsoft's new improved security by himself.
