Can iphone users tell what type of phone someone has just by calling them?

I know this is a silly question, but please hear me out. I met a guy off a dating site; we chatted via I'm's briefly-he told me he was chatting thru AIM on his iphone; I was on my laptop. We then exchanged cell#'s in the I'm's and then he called me and we spoke briefly on the phone. A few minutes later, we resumed our conversation back online. He then told me what type of phone I had (an Android). This immediately creeped me out, bc I never told him the make of my phone. I asked him to explain how he knew and he was vague. Then he said, "well, I told you I was a computer engineer". He made up some excuse about the software or app on his iphone, but the thing is I never texted him with my cell, so how would that be possible? The only interaction he had with my phone was when he CALLED.So, how on earth would a software or app be able to identify the brand of my phone? Am I being too paranoid? I mean, how would he have known the type of phone I had just by phoning me? Really creeped out. This guy has got me thinking he's capable of hacking. I'm not familiar with iphones or the apps or software, that's why I'm asking before I jump to conclusions. This is kind of off putting and I was hoping to give the guy a shot-he seemed really great up until this point!

I have an iPhone and I can't tell what other people's phones are unless they have an iPhone 4 or iPhone 4s - you can use iMessage between each other which is free texting to other iPhones. The message turns blue, to regular phone users it's green. The only thing I can notice is when I get a call I can see what area the phone call is coming from. Like the city and the state.

No he can't unless he has an iphone4 and you have an iphone4
