It almost comes as no surprise that once again, the HTC HD2 has received yet another major development update, this time along with the Samsung Omnia 7. Development team XDA-Devs Europe brings us a world exclusive—the first custom ROMs based on the forthcoming Windows Phone 7 update, codenamed ‘Tango’, officially knows as ‘Windows Phone 7.5 Refresh’. Tango is said to bring a number of improvements to Windows Phone 7.5, including lower RAM requirements and MMS improvements.
The two custom ROMs are based on Tango RTM build 8773.98, which will soon be shipping to OEM manufacturers. Both ROMs are almost fully functional. However, according to the devs, a number of limitations exist. The official Market is currently blocked on both devices, due to Tango not being publicly available at this time, though an alternative app is included. The ROMs are also not updatable at present, but this will be remedied in due course.
The HD2 custom ROM is brought to us by XDA Recognized Developer HD2Owner and can be found in the HD2 ROM thread. XDA Forum Moderator ceesheim has released the Samsung Omnia 7 custom ROM, which can be found in the Omnia 7 ROM thread.
