you take a new phone and sync all apps from your itunes account to your new iphone will it sync the apps up to date with the data or only what was in your last sync. For example you sync your iphone with itunes and your apps. Now from that sync you had 10 songs on shazam. 2 weeks later you have 50 songs, i know shazam stores tags in the cloud but when you restore your apps from itunes will it restore the tags from 2 weeks ago or just put the apps back on your phone and download all the data from the cloud.
