This week, AT&T launched the Tilt: what is being called AT&T’s most powerful smart phone for business users. Surely, this is a model in AT&T’s lineup that warrants a full marketing push and heavy promotion in the AT&T stores.

Yet, in every AT&T store you will find prime real estate dedicated to the iPhone display. AT&T and Apple have a 5 year exclusivity agreement here in the United States and since June 29th, the iPhone display has occupied the key spot in the store’s floor plan.

Walk into every corporate AT&T store and you will be confronted with the glorious white display with the LCD widescreen monitor turned 90 degrees displaying the various features of our beloved device. It is a painfully simple display—consistent with the modern minimalist approach Apple maintains in their Apple Stores. But contrasted with the rest of the AT&T store which is cluttered with blue and orange wall detailing, racks of accessories, and other phones, the iPhone display sticks out like a sore thumb.

In retail, sticking out is a good thing. Which makes me wonder: How long will Apple get top billing in AT&T stores with their own display? Will the iPhone eventually take a seat next tot he other phones in the AT&T lineup?

When I posed this question to my local AT&T store, they responded with, “We have heard of no such plans to take the display down. We take it down when we are told to.”

Not a surprising answer. It would be far-fetched to believe someone in the store level of the organization would have any say in what is displayed. Especially considering these are AT&T corporate stores. So I decided to call the main AT&T number to try and get some answers.

After 6 transfers and 32 minutes later I got a voicemail box. I left a message posing this question, “Hello, my name is Gregory Ng, Editor-in-Chief of iPhoneMatters.com. I was wondering if you could tell me if the iPhone displays will remain for the full 5-year exclusivity agreement with you guys. Or will the iPhone eventually enter the ranks of your other phones in your lineup and maintain space on AT&T displays?”

After 3 days, I have not received a response.

What do you think? No doubt, the iPhone has generated tons of new customers to AT&T and countless more to their stores. But how long will AT&T give Apple top billing?
