The Smartphone Experts S&C retractable sync and charging cable for iPhone [$4.95] is something Georgia took a look at recently for iPad and iPhone 3GS but, frankly, I needed a convenient, tidy, highly portable way to sync and change my iPhone 4 on the go and so I grabbed it. Literally.
The Smartphone Experts S&C Retractable Cable for iPhone expands to a length of 2 ft. and has a locking feature which allows you to choose which length you would like the cable locked at. A light tug on the cable and it retracts back to its wound state. When wound, the Cable is only 4.5 inches long, making it very easy to bring with you. My regular usb S&C cable was always a tangled mess when I carried it loose in my briefcase. A good deal of time and effort was spent on untangling the cord from whatever it had become attached to. With the Smartphone Experts S&C Retractable Cable for iPhone, charging and syncing my iPhone is a snap, just take it out of my briefcase and plug it in and when I am done a quick tug and is thrown back into my bag. The cable is quite well constructed and after a month of use it is still working like new.
It's also $4.95, so I'm not too concerned about lending them (which usually translates into giving them away). If you want to keep your iPhone 4 synced up and charged, check it out.
And check out Georgia's video after the break to see it in action on the iPad and iPhone 3GS. (Works the same with iPhone 4).
