IPhoto won't recognize my iPhone

Question

hi hello, all of suddenly my iPhone 3GS will not appear in my iphones when i sync to my iMac. Now I can't retrieve any photo's I've taken. There was no preference changes, and I already tried Applications>Image Capture>Preferences>Camera:when a camera is connected, open:iPhoto. ..nothing
Still iPhoto won't recognize my iPhone. What the heck happened?? and how to fix?
Thanks for your time, James

Try trash the following file
com.apple.ImageCaptureNotifications.DeviceDiscoveryDatabase.501
from HD/Library/ Caches
and restart your mac.
If that fails: try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
*What's the plist file?*
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
