Radio Shack sells mobile phones. It sells mobile phone accessories. And I'm pretty sure it sells plans on multiple providers.
And it has AT&T, so it makes sense for them to sell the iPhone. When I worked there decades ago, Radio Shack was cutting edge. But the company needs someone with a new vision. It's a bit long in the tooth now, sort of a poor man's Sharper Image. Since they've scaled back their electronic parts that used to be their hallmark, I rarely go there anymore.
Seriously though, "The Shack"-- is that for real?
That's my reaction, too. It wouldn't surprise me, though. But that name would spell the end of the company.
