I want to create space for iOS 6 update on my iPhone?

I'm currently at 1.4 GB open but I need 2.4. What should I do to lower my number without deleting my music and photos all together?

Erase the apps that you thought were cool for a day and then never opened again, should be a lot.apple is filled with useless one time apps.

Dude, this is not rocket science, just delete some stuff.

You can try deleting applications that you never use or don't use often. Try to back up your iPhone prior to updating it to another iOS. I'm sorry I can't explain it clearly-- it's because of broken iPod Touch.

Another thing you can do is compress.mp3 files into "Apple format" (I apologize again) (option available on iTunes) and re-syncing all the music to your iPhone. That can save about a few memory space depending on number of songs synced into the iPod Touch.
