I tried this yesterday just to verify it works OK, and it does.
It's an old debranded Omnia 7 UK firmware.
If you are fed up waiting for the T-Mobile Mango update this will work fine.
Bear in mind your phone will be wiped and you will lose everthing on it.
Just thought i'd post just incase anyone on T-Mobile is fed up waiting on their Mango and wants to give it a go.
But please remember, it's all done at your own risk.

Once you flash the Omnia, Zune will install the previous updates and finally Mango.
If the T-Mobile Mango update is actually out, please just ignore this update method and do it the easy way.
