Well. In UK the way you got beta was simple. You had a BTU version then you register and then the OTA update with beta was downloaded.
And that was the official way. By the way BETA version of 7.0 ( In UK) was ONLY available as BTU.
How many times do I and others have to say this. The beta in the UK was open to unlocked XEU. I know cos I registered.
My phone is unlocked, you don't have to be rude! Are you calling me a liar? ☹
Was your post directed at me. If it was I wasn't replying to you. I was saying that it wasn't just BTU that was able to get the beta in the UK.
Miss information is one of my pet hates.
