The iPhone Is Now the Most Popular Phone in the U.S.

The table can be used to skew the results. The author points out that a couple of iPhone versions are probably merged (3G and 3GS), apart from earlier versions, but that is not clear from the reproduced table. The Motorola RAZR V3s appear on one line, but have a host of variations. If all the RIMM phones listed were instead on one line, they would be a clear #1 at 5.3%. And any list of "the top 10 X's" where the top item is no higher than 4% should probably be a list of "the top 20 X's", or whatever, so that the "all others" do not constitute 79.5% of the total, as here.
Incidentally, my car (where I most need to use navigation) has a GPS unit, for navigation, and a radio for weather data, all accessible without taking my eyes off the road for over one second. Maybe all the people weaving around on the freeway are using their iPhones (or, of course, their Droids) to do those things?

Skype for iPhone: Beginning of the End For Mobile Phone Revenue Growth?

I get VOIP service on all our cell phones as well as our landline through a service called Tel3 (tel3advantage.com), where I dial a local number, it recognizes the callerID, (or I can log in via our primary number and a password), and I get Skype-like rates to any phone anywhere. From the landline, I use it for everything beyond local calls (so my POST is local only; NB 911 works as normal), and for the cell phones all international calls. Only problem is that it is from US only, though I have called it from abroad, to call another international number, only paying the semi-exhorbitant roaming rate + Tel3, rather than the full exhorbitant rate. Quality is usually very good, and they have a try-again routine that reroutes the occasional bad one.

iPhone Versus the Rest: More Evidence Smartphone Makers Are in Trouble

Maybe you could use the argument by which my wife and I have different cell phone service providers (I use T-Mobile, she now uses Verizon, having used the older AT&T phone technology till Cingular dropped it): Even though both of our services have significant service holes, most often one of the two will work, wherever we are!
