i have tried many times to unsync photos from my iphone and just getting nowhere
Are you saying you have de-selected Sync Photos under the Photos tab for your iPhone sync preferences with iTunes followed by a sync and all photos transferred from your computer via the iTunes sync process are not removed from your iPhone?
yeah basically it will then come up with an option of remove photos or keep photos i click remove and nothing happens
Nothing happens after selecting Remove followed by a sync?
If so, you may need to restore your iPhone with iTunes with Sync Photos deselected under the Photos tab before your iPhone's backup is updated.
