Apple & Mac Devices using 5 Ghz 802.11n

[exthree]

I'm in the market for a new home office router and trying to figure out if I need dual-band 2.5 and 5.0 Ghz frequencies for wireless 802.11n/g. We use both PC and Mac Book laptops, iMac desktop, iPad and iPad 2, iPhone 4 and 4S, and a Blackberry.

There are some new routers out there by Cisco (Linksys) and Netgear that provide simultaneous 2.5 and 5 Ghz, but I don't know the frequencies my devices use!?

Any recommendations on a router BTW?

depending on how old the iMac and macbook pro are they may support the 5ghz. not sure on the original iPad but i know for sure iPad 2 supports it. and no iPhone supports 5ghz at this point either.
