Since we got a whiff of Windows Phone 7, there has been a fair amount of speculation regarding a release date. There was a hint that an October Telstra launch was on the cards with some even expecting the Window Phone 7 to be released this July.

Well, it would appear that a July release date may not be far from the truth, if this AT&T signage is anything to go by. This piece of signage, revealed by Engadget, shows a space labelled ‘Windows Phone 7′ is rumoured to be sent out for a July 24th store overhaul.

If this piece of signage is the real thing, then this will definitely help raise the stakes for Windows Phone 7 to improve their foothold on the OS market, which is currently dominated by the likes of Apple and Android.
