I just jailbroke my Iphone 3gs, firmware 4.2.1 and now baseband 6.15.02, using redsn0w. I then downloaded ultrasn0w to unlock it. After reboot the phone went into recovery mode and will not reboot using tethered reboot in redsn0w.
Redsn0w gets to the end of the first stage, waiting for reboot, the iphone starts to reboot then I get a white screen and an unexpected error. Afer about 10 minutes the white screen goes away and the phone appears in recovery mode, "please connect to itunes" image.
I am on a Mac with osx. Any and all help is greatly appreciated.
Also I do not have any blobs saved.

Thanks to all who may be researching this, I finally resolved the problem using greenpoison to jailbreak again and then redsnow to install cydia. The phone is unlocked and working now.
