iphone 4 charges but won't connect to macbook

I have an iphone 4 that I manually manage using a 2009ish macbook. The phone charges when plugged in through the usb port, but does not show up on the computer.

I've tried the following on a mac and a pc: reinstalled itunes, restarted computers multiple times, rebooted (hold down home and lock buttons) iphone twice as suggested on another forum, used a different usb port, used a difference usb cord, installed yosemite, new iphoto, new itunes. It didn't work with old or new osx or iphoto or itunes.

If this has anything to do with it, I recently (don't think I've tried syncing since) moved all my pics from iphoto to an external hd to free up space on macbook.

Thanks!

The only thing left to try is to connect it to a different computer to see if iTunes will detect it. If not, then I *assume* you have a defective dock connector on your iPhone. If you live near an Apple Store, have them diagnose the problem for you.
