Permissions help!!!

so, my new MBP 13" decidied it wasnt going to sync my iPhone. I had a problem earlier with not being able to access files.

when i first got the MBP last weekend, i installed my user from a manual back up of my MB. everything was fine with it until i tried to save stuff. i changed permissions to the user folder and everything worked.

this, time there were some errors trying to sync my phone. so i figured that i would change permissions and ownership of the Macintosh HD.

now the MBP will not boot. i can get single user mode. everytime i perform a UNIX command this appears and then what ever it can do is printed:

shared_region: 0xffffff800a7ecba8 [24(ls)] map (0xffffff800ab788b8: 'dyld_shared_cache_x86_64'): owned by uid=501 instead of 0

can anyone help?

TIA
Dylan

Hey, have you tried booting to the Install DVD and using any of the disk repair tools?

Here is a walkthrough for do that:
Mac OS X - Using Disk Utility to Repair a Disk

I am not at home and i had to take it to the apple store. they did an archive and install. everything works, except the iphone is not picked up.
