Why not use this opportunity to learn more about what makes your iDevice tick? IPhone tinkerers have been opening up their handsets for years, both literally and figuratively.
Why not try jail-breaking your iPhone, a process that has never been easier. With a jail-broken iPhone, you will have access to a wide array of apps not found in Apple's closed iTunes store, some of which might allow you to change the appearance of your phone's interface, gain access to deeper system functions, synchronize with iTunes over the air, and more.
Or, if you're feeling adventurous, you could crack open the phone's case and get at its innards (a process which will almost certainly void your warrantee). The iPhone is packed with an impressive array of antennas, processors, and sensors – and could be the perfect source of parts for your next geeky, DIY project.
