Q: how do i find my photo stream from my old apple devise ? it shows in my manage storage i have a different deivse backed up in september but i cant find those photos

Photo stream photos are not included in your backup, only camera roll photos are.  Photo stream photos can only be accessed from an iOS device or computer that is signed into your iCloud account and has photo stream enabled.  However, they only remain in iCloud for 30 days; if the photos are older than that they are no longer available to download.

If the photos were in the camera roll on your 3GS when you last backed it up, restoring the backup to another iPHone should recover them.  If this is an iCloud backup, you'll need to do this before the backup is 180 days old or Apple will delete it.

If you need to restore the iCloud backup to your 4s, back up your 4s to your computer using iTunes, then restore the iCloud backup of your old phone to it, import the recovered photos to your computer (as explained here: http://support.apple.com/kb/HT4083), then restore your phone to the iTunes backup your made earler to recover your data.
