Would an iphone 1 or 2 still work today?

I'm looking to replace my phone. Right now I've got an Android HTC Inspire and it's cool, but it restarts itself like every hour and I think it's dying.
I don't use it as a phone for calls. I just took the SIM card out of mine. I use it to check email, use the gameboy emulators on it, and search the internet on it.

Would I still be able to use those things on an older model iphone?

They work on a nokia 3310

Yes.

Yeah. They both would.
