Here are some products which can make it easier to sync your iPhone or connect it to other accessories.
iStubz are short iPhone syncing cables – The white sync cable which Apple includes with all iPhones, iPads and iPod Touches is about 3.5 feet long. I find it too long and cumbersome at times. Instead of using this long cable, I now carry an iStubz cable which doesn’t get tangled. iStubz are available in two sizes 7cm and 22 cm which are about 3 inches and 9 inches, respectively.
Apple iPhone Dock – I like to have my phone standing upright when my phone is sitting on my desk so I can easily see and read the screen. One way to keep the phone upright, while also charging and syncing the phone is to use an iPhone Dock. Apple no longer sells the Universal Dock which worked with older iPhones and iPods, but they do sell the Lightning Dock which works will iPhone or iPad with a Lightning connector.
dockStubz and dockXtender – If you keep your iPhone in a case, you may find that the case makes the phone too thick to fit into a Dock. Alternatively, the iPhone’s 30-pin Dock connector might be too recessed inside the case for some iPhone accessories, like a car charger, to be able to reach it. dockStubz is a short extender which would let you connect the car charger or other accessory. The dockXtender is a short cable which would let you connect your thick iPhone to connect to an Apple Dock or other accessories.
