In the next six months, a lot of things will change. The weather will shift, and fashions will follow accordingly. We’ll all be treated to (and hopefully have our film-lives changed by) highly-anticipated blockbusters like The Dark Knight Rises and The Avengers. By the end of that time period, the entire political landscape in the United States may have changed, as we will be nearing the end of a sure to be brutal Presidential campaign.

But one thing won’t change. Teens will still be obsessed with iPhones.

Around the same time last year, we told you that teens be iPhonein’. One year ago, a Piper Jaffray survey found that 17% of the teen market belonged to Apple’s device and at the time 37% of the teens surveyed said that they planned on buying an iPhone in the next few months.

In the Fall of 2011, the same survey showed that 23% of teens owned an iPhone and 38% planned on getting one.

Now, Piper Jaffray has released the Spring 2012 results of their semi-annual survey, and it should come as no surprise that teenagers still like Apple. In a survey of 5,600 students with an average age of 16.3, 34% now say that they own an iPhone. That’s double what was reported just one year ago.

Furthermore, 40% say that they plan on buying an iPhone in the the next 6 months.

In that 6-month time frame, we might just see the launch of the iPhone 5 (or new iPhone, or whatever). A string of recent reports paint the launch window with a broad brush, saying that somewhere in September to October is looking like the time. A recent rumor out of Foxconn gave an earlier date, however. Those sources pointed to June.

The release of the iPhone 4S, with its lack of outward modifications, led some to ask if the iPhone was becoming uncool. If teens are driving the “what’s cool” trends (and that’s highly debatable, mind you), then it’s hard to say that the iPhone is losing any of its cool factor.
