With Build starting tomorrow there are some last minute rumors surfacing. This one for instance, The Lumia 930 will be at Build but will not have Windows Phone 8.1 on it. This rumor would only make sense if there was a last minute issue with 8.1 causing it not yet to be compatible with the Lumia 930.
We give this rumor a 50/100. I do not think Nokia would release the 930 without 8.1 on it, but that is just my opinion. Let us know what you think or what you might have heard about this, and get ready we should have some big news tomorrow.
