only issue I had with my blackra1n is it didn't like stuff on my phone. I had to restore to perfectly clean, jailbreak, then restore from backup to get my stuff back.
I recommend trying that. Also, make sure you are running the latest iTunes and follow the instructions completely. Remember, when only need iTunes open long enough to put the phone into restore mode, close itunes after that. You shouldn't actually do anything in iTunes with blackrain.
