Ever since the Lumia 900 made its debut at CES, AT&T, Microsoft and Nokia have all stayed mum on the availability details of the new Windows Phone, saying only that it'll be launching "in the coming months." That hasn't stopped spitting out possible release info from slipping out, though, and today we've got another report to add to the pile. The folks at BGR claim to have gotten hold of a partial AT&T 2012 roadmap courtesy of a "trusted source" and, according to said roadmap, the Lumia 900 may be priced at $99.99 on contract when it hits. The report adds that the 900 is currently expected to be coming on March 18th, though the site adds that that could change since the phone hasn't earned technical acceptance yet.

This isn't the first time we've heard rumors of a March 18th retail debut for the Lumia 900, but the fact that it's popped up again seemingly adds a bit more credence to the date. Of course, release rumors are just that, rumors, and launch dates can occasionally change before they're set in stone. As for the 900's alleged $100 price tag? That'd make it quite a bit cheaper than AT&T's other LTE-enabled handset offerings — the HTC Vivid and Samsung Galaxy S II Skyrocket — which are both currently going for $200 on the carrier's website. Nokia has indicated in the past that it wants to make a splash in the U.S. market with its Windows Phone devices, though, and a $100 Lumia 900 would certainly help it achieve that goal. Would you be interested in picking up a Lumia 900 for $100 on contract? Just in case you need help while pondering your answer, our hands-on with the 900 is available below.
