A little more information would be helpful. You might try restoring your phone. If all else fails... contact Apple... as it's still under warranty.

Been dozens of threads in the last month for that…

More info would've probably got you more results

And this.
 
If you downloaded the tweak 'substrate safe mode' you might have a chance.

If not, a restore may be your last shot. Which means no jailbroken phone for you until 5.1 jb is released.

Probable that your bootloader got fragged with a recently downloaded tweak from Cydia??? If you can get past the boot logo an into safe mode via substrate safe mode, you could delete the offending tweak.
 
I was finally able to get it to boot by tethering it to my computer, not sure whats up with that...I should not have to do that for this jailbreak.

I wasn't sure what other info you needed figured everyone would just ask if they needed more, and my phone doesn't keep booting, it just freezes (for good) on the apple logo.
 
anyone have any ideas?

is this happening to anyone else?

If u updated most of the important tweaks via cydia, you can shutdown ur phone by holding the sleep button and home button till phone turns off
Then when u turn it back on then immediatly hold the volume up button until u get back on to the lockscreen hold it a couple of seconds after for good measures.
This method will put u in safe mode and usually delete the last tweak u download off cydia or maybe the last couple of tweaks.
