Mobile Lowdown: 6-22-11: iCloud; Samsung/Apple Suit; Flickr; AT&T; Best Buy

A look at some of the big stories in mobile today:

iCloud: The good news for Apple (NSDQ: AAPL) is that 76 percent of iPhone owners say they will be using iCloud and 30 percent will even give iTunes Match a spin. The bad news is that Apple seems to be having some trouble holding on to key executives running the new initiative.

Samsung/Apple: Samsung won’t get to see Apple’s products before the rest of us; but it also looks like Apple might also not get the injunction it was seeking on Samsung’s products. Here’s the latest on the two companies’ patent and trademark lawsuits.

Flickr: New data shows that the iPhone 4 is the most popular camera on the popular photo sharing site Flickr, but because photos sent via apps don’t get counted, some think that its margin of leadership is even bigger than Flickr says it is.

AT&T: Verizon may be gearing up to end its unlimited plans, so that gives AT&T (NYSE: T) the perfect opportunity to launch one of its own for prepaid users: $50 all-in.

Best Buy: Not to be outdone by Google (NSDQ: GOOG), Amazon (NSDQ: AMZN), Apple and the rest of the cloud bandwagon, Best Buy is now also expanding its own services up in the sky: it’s extending its Music Cloud service, first started in the UK, to the U.S. market.
