Remember when ChevronWP7 hit Windows Phone 7 which allowed to jailbreak Microsoft's latest mobile OS to allow the installation of homebrew apps? Well, not long after ChevronWP7 was released, it was taken down again by Microsoft's request but the developers around ChevronWP7 and Microsoft came together to discuss and work on a solution to make it more official, more Microsoft supported and less jailbreak. After a first Beta, which totally crashed the servers, ChevronWP7 is back again - now called ChevronWP7 Labs - and as the original ChevronWP7 it brings any Windows Phone to a kind of developer status which allows to run homebrew apps - not available from the Windows Phone Marketplace.
Furthermore, ChevronWP7 Labs now supports Microsoft's latest Windows Phone 7.5/Mango version but unlike before, it's not free anymore but costs US$ 9.00. This gives the user a "token" which can be used for one Windows Phone (keep in mind that this token isn't transferable to another Windows Phone after a - let's say device change) which needs to be installed. Furthermore, ChevronWP7 Labs requires a Windows Live ID (most Windows Phone users should have anyway) and Microsoft's freely downloadable "Windows Phone SDK 7.1".
ChevronWP7 Labs is charged via PayPal but also accepts credit cards (which are processed by PayPal) in case you don't have a PayPal account.
Just as a friendly but serious reminder: ChevronWP7 Labs isn't designed to run stolen apps but it's designed for hobbyists and experienced users which want to try out and Beta test homebrew apps! So please be fair and pay developers for their work!
