How do I re-sync my Photostream between devices?

Hi All,

I recently had to do a restore-to factory settings on my iPhone 4s ( 5.1 iOS ), to solve a bluetooth issue. I then re-installed all my apps etc. so it's pretty much back as before - including iCloud with photo stream.

All worked fine except Photostream. Prior to resetting the phone both my iPhone & iPhoto Photostream files were in sync - both showing 148 files.

Now on my iPhone the Photostream album only contains 30 of those files.
How can I get the iPhone back in sync with my iPhoto files?

cheers all

Solved - sort of...

I cured it this way.

Copied all the Photostream images in my iPhoto PS album to a new iPhoto album.

Deleted all photos from my iPhoto PS album. These then deleted what was on my iPhone PS album. So effectively I had no PS images in either my iPhoto PS album of my iPhone PS album.

Then copied all the PS images I'd saved earlier back to my iPhoto PS album, which then synced to my phone.

Both PS albums now match.
