I have just been to my local Currys and purchased this IWANTIT USB Sync & Charge Cable 3m for only 97p came home and checked online it's the same price it's a bargain you can use it as a spare or main as it's 3m as well so it has lots of cable for less than a pound it can keep your Apple devices fully charged and synced with the iWantit USB Sync & Charge Cable.
Please don't vote cold unless you can find a better cable with a brand name and cheaper price as it's a deal I thought deserves heat. It's online as well as Instore it could be a misprice because if you scroll down the page the same cable Currys are selling for £12.99.
With a cable length of approximately 3 metres you can enjoy plenty of freedom when your device is connected.
A handy spare or perfect replacement, the iWantit USB Sync & Charge Cable is compatible with iPhone, iPad and iPod connections.
