    So, does it finally support 2.4 AND 5GHz N wifi? Can someone confirm?

    No, only 2.4Ghz. Only the iPad supports 5Ghz.

    I've read on another forum that an iPhone 4S can connect to a 5GHz router, but only because it's 'backwards compatible' (their words); but it'll operate in the 2.4GHz band. I assume this is only true if it's a router that supports both bands simultaneously?

    In my case, my iPhone can't even see 5GHz networks, but the network immediately becomes visible once the band is switched to 2.4GHz. I'm guessing I have one of those cheapo routers without that feature.

    Interesting, I have a Linksys WRT110, which has "N" But when I switch it to "N Only" I can't connect to it, I went through the settings, and all of the settings for N Transmission were around 2.4GHz. Old Router. It just won't connect. I've set it to "Mixed" and I can connect.
