Here are the apps that I deleted from the Photon 4G so far with no notable problems, using Titanium Backup after rooting:
(Make sure you back up your original rom first!!)
IMPORTANT REMINDER: As you remove each app with Titanium Backup, remember to WIPE DATA for EVERY app prior to removing that app...and then when you are all done stripping everything out, reboot to your recovery and clear your Cache and your Dalvik Cache!

Anyways, be sure to make a CWM backup of your stock ROM before stripping, and I would suggest making a copy of your stock System/App folder prior to stripping and put it on your SD card so that you can re-add system apps if you want to use them later. (Like adding your SIM card management apps back when you travel overseas, etc...)
Enjoy!
