Rumors have become an inseparable part of our daily routine, but are all rumors groundless? Definitely no. And now a new rumor is circling around — according to Windows SuperSite the Nokia Lumia 900 will have an exclusive launch period at AT&T only 45 days. Afterwards, other carriers and retailers can also sell the device, of course if they wish.

Moreover, the source claims T-Mobile is on the list top and will offer the Lumia 900 sometime in Q3. To remind you, according to initial information, AT&T will start offering the third Nokia Windows Phone smartphone on March 18. Another rumor not less interesting claims T-Mobile Nokia Lumia 900 will sport a 12MP camera unlike AT&T’s version coming with an 8MP one.

In all likelihood, the next carrier to have Nokia’s latest flagship in its portfolio will be Verizon Wireless. Perhaps, Sprint will offer it too. At&T doesn’t consider it beneficial, but Microsoft and Nokia are spending a huge amount of money on promoting their joint productions. So there is a possibility this rumor will turn out to be true, at least partly.
