Deal or no deal? This is perhaps the biggest question looming around the AT&T and T-Mobile merger that is still under review before the justice department for monopoly issues and technicalities.  AT&T has already responded to government’s probes and assured the state that it would be bringing in thousand more jobs once the contract is sealed. Although this battle may seem to be the telecommunications giant’s focus presently, AT&T has not forgotten to beef up their portfolio, having just presented a wave of Windows Phone 7.5 or“Mango” phones to the marketplace.

Senior Vice President of Devices, AT&T Mobility and Consumer Markets, Jeff Bradley mentioned the catalyst such a launch, consisting of three new phones at the same time.  He noted, “Our customers love Windows Phones which is why we’ve sold more of them than anyone else. We’re taking our leadership to a whole new level by getting the Mango update to all existing customers and rolling out awesome new Windows Phones.”

The announcement formally injected Mango Windows-powered phones into the AT&T family, which now includes the Samsung Focus S, HTC Titan and Samsung Focus Flash. Mango was first sent to manufacturing last July, and anticipation of a full launch escalated into the fall season.  In this light, 4G Windows phones from Samsung and HTC will also be released by fourth quarter of the year.

To date, AT&T is the carrier that sells the most number of Windows-based phones. Other developments within the company involve refurbishing stores in line with the upward thrust on tablets, selecting Acer Iconia on that front.

In order to support this growing ecosystem, and in an effort to remain a leader in the mobile era, AT&T has invested quite a sum of money for the T-Mobile acquisition.  They have a sold mobile security platform to fund T-Mobile’s world tour talks.  The longer the delay of the US government’s decision, the more concerns continue to pile up.  Should fate turns its back on AT&T, this could spell a most painful setback for the leading telecommunications company. Otherwise, the two powerhouse combined will pose a threat to competitors, big or small.  But while they are still waiting for legal decisions to take place, introducing updates in the market, like these Mango phones, can make shareholders less tensed about the organization’s stance, especially as Microsoft looks to usher in a new era of smart devices.
