What does the body language tell me?

I was in an Apple store today and I was bent down on the counter trying out the iPhone 5. My sister went off to check out something else. A few minutes after, I straightened up and turned around and there was 2 boys staring at me with sly smiles on their faces. They didn't look away when I looked at them or anything. I felt awkward, so I just turned away quickly and followed my sister.
This incidence isn't important, but I it wouldn't hurt to know what it means for future reference, I guess, haha.

Worth picking up an Iphone 4 for $279?

It's not the S model, I don't believe, but is that a good price? Or can I find something significantly better for the price? If so, please drop some names for me. Would prefer if this was an established brand - respect by both buyers and tech-savvy reviewers (Cnet.com, etc).
