To jailbreak an iPhone 4 you need to download redsn0w. For better info go to youtube and search ' how to jailbreak iPhone 4 on (whatever your OS is .example: IOS 5).'
Your iPhone 5 should play both Facebook and YouTube videos over 4g. You should try to delete your cache and cookies in the settings to see if that works.
