iPhone App device name / file prefix

[Calego 0]

I have installed the app for my iphone and set it to sync my photos to my PC.  When I started syncing my photos, it used the default name of the iphone device as a file prefix.  In my case, my iphone was set as "Alex's iPhone" so each image file has the prefix "Alex's_..."  Apparently it limits the device name to 7 characters.  I didn't like that so I changed the device name in the iphone app to "iPhone."  However, that did not change the file prefix of the synced photos to my PC.  It is still using the old name as the prefix.  How do I change this?  Thanks.

This isn't the section for sync.
