We first broke the new about the Nokia 'Sabre' last month--namely that it was in engineering for tests, that it has a 3.7" screen and Micro SIM card. Besides that we also had the name 'Sabre' which till now, has not been verified anywhere else. Going back even further, one Micheal-Dallas in our forums mentions the 'Sabre' back in July, noting it's for AT&T in Summer 2012 (we think that's too far out).

Now, Microsoft Canada has accidentally leaked the name in the rules for a Mango-app contest. From the page itself, it notes:

"The estimated retail value of the phone is $600.00. The type of Windows Phone 7.5 will vary and will be selected at Microsoft’s choosing (examples include Samsung Yukon, Samsung Wembley, NOKIA Searay and NOKIA Sabre)"

Interestingly, only the Searay is the familiar one out of the bunch. The Yukon and Wembley are also unknown devices, presumably variants of the Omnia W and Focus S. The Sabre however, is new and evidently different than the Searay--perhaps a mid-range offering. All we know is what we already mentioned above: Micro SIM, 3.7" screen. Interestingly, Vodafone is adopting Micro SIM cards soon, something we and Pocket-lint think will be for new Nokia Windows Phones.

Good thing we'll learn more in late October at Nokia World.

Update: That was fast. Microsoft Canada has now modified the page and removed the device names. See our screen grab for the old version.
