IPhone 4 fix, Stuck at apple logo?

My iPhone 4 is on ios 6.0.1 and everytime i try to turn it on it will always stay on apple logo, It worked fine after my phone was completely finished jailbroken from Redsn0w program with the ios 6.0. Cydia was install perfectly and all that. I installed a few other programs from cydia such as siri etc. Now when i turn it on, it gets stuck on the apple screen logo.

I'm able to successfully load the ios 6.0 from latest Redsn0w with the "Just Boot" And it turns on and works perfectly fine. But when i wanna restart my phone, it get stucks on the apple logo. Is there a fix to this? My computer says the phone is perfectly connected to the computer and i'm able to view files and such. So i know it still loads up, just stays suck on apple logo. Is there any fix to this?

Its a tethered jailbreak, everytime you restart or battery dies you will need to hook up to a pc and use redsn0w just boot.
