In today’s Mobile News, we do a little Tango and trip over a RIM bump. Care to join us?

Windows Phone Tango OS Eases RAM

Windows Phone 7 is upgrading its OS slowly. The Mango version gets an upgrade to Tango, which is rumoured to be very easy on RAM capacities, which would seem to ease integration with the multiple tiers of Nokia mobile phones.

Windows Phones have a minimum system requirement of 256 MB, so that’s a familiar figure to industry experts. However, many mobile phones and smartphones being developed today often have at least 1 GB of RAM – at least for mid- and upper-tiered models.

Nokia has a very large market following in the low- to mid-tier model users, though. As the Windows Phone flagship carrier, Microsoft wants to enable its WP compatibility to all market ranges, and it has adjusted the Tango OS update to tiptoe lightly across a 256-MB RAM system.

How systems operations and graphics will be affected by this parameter will be seen as the Tango update gets released in the second quarter of 2012.

RIM CEO Replacement Not as Expected

The world was a buzz late last year as analysts speculated on RIM’s hints that a female would take over the joint positions of departing co-CEOs Lazaridis and Balsille. While the pair did resign as expected, but the rejoined CEO hat was taken up by someone that industry insiders and outsiders never expected. Or if they did suspect, they never leaked a hint.

Last year when RIM hinted that Barbara Stymies would probably be tapped for the CEO position, the stock market reacted very favourably, experiencing an overnight gain that had long been missing from RIM.

As the world awoke this morning and discovered that it was Thorsten Heins in the CEO position, stock prices dropped once again.

Stymies assumed a role as the Chairman of the Board, and whilst the ex-CEOs found themselves holding new titles on the Board of Directors: Lazaridis is now the Vice Chairman of the Board, and Balsille holds the title of Director of the Board.

Future history will determine the wisdom of the shuffle choices.
