I have an iphone 5s running ios7 and have just bought a second-hand 3GS to use as a decent spare phone to swap the sim over to, which I can be more relaxed about the prospect of losing or damaging. The trouble is - am I able to get my icloud-saved contacts, apps and other info onto my new, older phone, which is running ios 6? If so, how do I do this? Thanks.
