The fix for the camera connection issue is available as an ‘Essential Upgrade’ in Cydia. Saurik has tweeted:
So, @comex made some fixes to the kernel patches for JailbreakMe, and we are pushing them as an “Essential Upgrade”… I hope this works! 🙁
To be clear: do /not/ go back to jailbreakme.com and “redo” the jailbreak; instead, just open Cydia, and accept the new “Essential Upgrade”.
Users whose Verizon iPhone is stuck at the Apple logo after using JailbreakMe 3.0 have two options to fix the issue:
Hold down the home and power buttons until you see “Connect to iTunes”, then use iTunes to restore to the latest firmware. This will lose data stored on the phone.
Apply a quasi-experimental fix using redsn0w. Download:Open Redsn0w, select your IPSW, choose “Install custom bundle“, and select the fix bundle. Then follow the directions. If it works correctly, after installation your phone will boot normally.
Comex had previously also fixed the ‘Cydia Disappears’ issue.
