Now, thanks to Charmin, users can download free mobile applications for iPhones and BlackBerrys that use GPS to show you the way to the nearest public pit stop. Not only will you get location, Sit or Squat also lets users rate each restroom based on ick-factor (an average rating above 2.5 is “sit,” below “squat”) so you can avoid less than stellar accommodations (if you have the luxury of being picky).

Being a toilet paper company, this is obviously a great fit for Charmin, and it’s getting them a lot of buzz on blogs and other traditional media outlets-which is the point, of course. What’s so interesting about it though, is that Sit or Squat was a pre-existing site – the lesson being that you don’t necessarily need to be a corporate giant for a good, common-sense interactive site or application to pay off. Certainly, Charmin’s saving some cash by avoiding the cost of custom application development and Sit or Squat now has a corporate sponsor to finance their brainchild and tell the world about it. It’s a win-win.

My second take is that I can’t decide whether this is a positive commentary on iPhone users (i.e. they know useless crap once they’ve seen it and never look back), or a somewhat less flattering one (they have an endless and apparently purposeless appetite for the latest gimicky digital froth).

I dunno. You guys tell me what you think.

Full disclosure: The device in my pocket was purchased when you still called them “cell phones” and they all had hinges in the middle, so this post might just be my pent-up gadget-envy lashing out at my luddite wallet.

Some interesting facts in here. I was kind of surprised that Yahoo Mail is the most popular mobile website in the US and that the Motorola Razrs (curse them) are the most owned devices among mobile internet users in the US.
