My iPhone 4 couldn't do this. Not only does the iPhone 5 do it, but it locks on within ten seconds! The GPS chipset in the 5 must be highly improved.
("SIM Locked" is a trick I learned; setting a SIM PIN lets you disable the cellular radio while keeping the GPS on. Using airplane mode kills them both)
