No, you can build against the iOS 7 SDK and still support older versions of iOS. With Xcode 5 you can only build against iOS 7. You can also have entirely separate functionality for different OS versions in the same app bundle. I've never tried it, but as far as I'm ware, you could theoretically build agains iOS 7 and have the app run on iOS 2.0, assuming the App Store still works.

Deployment targets earlier than 4.3 require armv6 libraries to support all devices, which Apple no longer ships. One can build an armv6 slice using an older toolchain and lipo it with armv7/armv7s slices built against 7.0, but it's not clear if Apple will accept such binaries as App Store submissions.
