Just check in iTunes >Edit >preferences >Devices >Device backups. If you have a backup made after the time u added/took photos, they'll be there after u restore & set it up with that backup. The photos will still be there if u have a recent backup, if not then sorry to chime in. Jfyi if u need to unlock or preserve bb for future resale value, create custom ipsw with redsnow 0.9.10b3 & pWned DFU, if no unlock needed enter dfu & just restore & use the backup.
If u wanted to stay on ios 4.3.3 u need to start tu, set hosts to cydia, close tu, open tu & start TSS server. Either way you'll need a recent backup in iTunes to recover photos.
