It’s no secret that ROM development is considerably more cumbersome on Microsoft’s closed source Windows Phone 7 operating system than on its open source competition. Despite the difficulties, developers on our site such as -=Barin=- have made outstanding progress with releases such as a fully functioning kitchen for HTC devices.
Unfortunately, however, this is little consolation for Samsung device owners. The sad reality is that in the fourteen months since the Samsung Focus and Omnia 7 were released, not a single custom ROM has been cooked. However, thanks to hard work by XDA forum members Cotulla and mwang, this is no longer the case. Based off Windows Phone 7.5 Mango build 8107, the Freedom series of ROMs gives first generation Samsung device owners what they’ve wanted from the very beginning.
As with any major OS modification, users should proceed with caution and read all available documentation. Those interested in loading up custom Mango goodness on your Samsung First Generation device should proceed to the Sammy Rainbow thread to get started with the MAGLDR. Once this has been done, fast forward to the Focus Rev1.3, Focus Rev1.4, and Omnia 7 ROM threads.
