With a Dual Band Time Capsule, can devices communicate from different bands through the time capsule?

I have an iPhone 3Gs and an iPhone 4 that I wish to 'communicate' with my iMac which is set up to run on a 5Ghz 'N' network.

Will the Dual Band Time Capsule allow this to happen?

I am thinking about this all in relation to the iCloud and iOS 5 where the iPhones will be able to do wireless backups to my iMac, but don't work on my Airport Express 5Ghz 'N' network. Will a Dual Band TC or Airport Extreme solve this problem?
