Surround Doesn't Dance
Not on my Surround.Tango update appears to be going to 2nd generation devices first. The way AT&T operates we'll be lucky to have it before MS pushes 7.8 OTA update, if ever. If we don't have Tango by then I'm not sure if 7.8 would be applied.
This would leave many users out of the loop, those who do not wish or are unable to install cabs, unbrand or unlock their phones.
I'm considering downgrading my bootloader and installing a fully unlocked custom rom. Hopefully I don't brick the phone. I have tinkered with it before using ChevrobLabs and interop unlock. My tech skills are not top notch but I am sick and tired of the lack of carrier support. The least these chuckle heads could do is to keep your phone up to date while you are under contract. This is entirely possible, but their lack of commitment is highly evident.
