Ok this question will of probably been covered many times before but being a noob I need to ask.
I've pre-ordered the iPhone 5 and will continue to use my iPhone 4 till it arrives. Like most people I will then look to sell my old phone to pay for the upgrade, however i'm a little unsure as to how I transfer all my old data, apps, photos, contacts etc.. to my new phone when it arrives.
I no longer have a pc so all my backing up is done through iCloud when I charge my phone.
How do I transfer my data and settings to my new iPhone?
