iPhone does not work! Mac does not recognize!

[Erobs16x]

I jailbroke my iphone today for the first time, it worked and then when i went to download a them it told me to reboot my device so i did, it turned off. Then it had the apple logo for an hour, from there i just held the standby key till the logo went away. Now it will only show the apple symbol and not turn on. I plug it in my mac and it shows the logo but it does not show up in iTunes!!!! I'm freaking out please help me!

im assuming that you used blackrain for your jailbreak so i'll ask you this: did you try running blackrain again?
