I have a Samsumg B5310 phone, and under F13, connecting it with a USB cable caused gphoto to be launched, which then allowed me to transfer photos from the phone to my laptop.
Sometime during the last two months I have lost that ability; most likely when I upgraded from F13 to F14. Now, gphoto is no longer launched when I plug the phone in, and when launched manually, gphoto doesn't "see" the phone: i.e. "import from removable device" doesn't list any devices.
Note that this phone doesn't (and didn't) appear as a mass storage device.
Here is the content of /var/log/messages, before and after, if its of any help:
