Mobile Boarding Passes are a go on the iPhone, BB, etc.
 

When you are traveling on select itineraries from Chicago O'Hare (ORD), Los Angeles International (LAX) and Santa Ana John Wayne/Orange County (SNA) airports, you now have the option to have your boarding pass sent directly to your mobile phone or other mobile device – saving paper and time. Eligible itineraries include non-stop flights with only one passenger listed in the record locator*.

Amazing what one can read here.

For the OP, if you are wondering at the lack of excitement, try searching before posting 'new' news :)

Very hard to get the first post on any announcement so worth checking first, in this case a search on 'mobile' will take you where the rest of the conversation is to be found .
