In addition to the sciatic nerve, many other nerve roots in the lumbar spine transmit nerve signals to the legs. Therefore, a bulging disc at any point between the five vertebrae of the lumbar spine (L1 to L5) or between the bottom of the lumbar spine and sacrum (L5 to S1) could result in leg pain.

With the phone set to airplay mode (and Wifi offed) the battery can last at least 3 days, when playing music ~10-12 hours a day (earphones, not speaker). The last I tried with 3G on and an active sim card, the battery could only last maybe 6-7 hours on regular usage. Conclusion: The hardware outlasts the technological advancements. Getting 3 years out of the phone shouldn't be a problem, though of course you'd be missing out on all the new features implemented on newer iPhones.
