Just got my Photon and ive been impressed. I'm starting this thread to make a list apps that worked for my Epic, but are having problems with my Photon. Could be a Gingerbread issue. If you guys have anything else to add, feel free.
*Spare Parts - battery history causes the app the force close
*Skype - can't seem to get the front camera to work, but it opens just fine
*youp3 - this just would not install period
*ringtone maker - this can't seem to install, so I had to get another one
