IPhone 4 Bricked Apple Logo

Tomorrow I'm travelling abroad and giving the phone to a member of family. Yesterday I downloaded SiriPort for iOS 6 (my iPhone 4 is Jailbroken on iOS 6.0.1) When it respringed, it went into an infinite apple loop. I know I must restore my phone in order to fix it but I really NEED to recover some photos. I connected my iPhone to iFunBox and started copying photos but then it said the device has been disconnected and is not coming on.So, yeah, its in an infinite apple logo loop. Please please please help!

Try reseting it. Hold down power and home button for 15 seconds

Hey don't be panicked. Hard reboot your iPhone again by holding the home button and the sleep button then as it boots up with the apple logo immediately hold the volume increase button till your on the lockscreen again. Then go onto cydia and unistall Siriport or any app that you recently installed then reboot it again.
