Stuck on apple icon! Heeelp!

[Ginahr]

So i jailbreaked my phone and it worked. I then downloaded a theme in Cydia, and when it was downloaded i also suddenly had Winterboard. So I clicked on winterboard, and it said that I had to reboot my phone or something. I did that, and now it wont turn on! It just shows the apple-sign. It showed the apple sign until it was out of battery, and when I plugged it in, it only showed the apple sign again. I can't do anything with my phone!! When I tried plugging it to the computer, the phone did not show in iTunes..

Does anyone know what I can do?
PLEASE HELP!

Did you have a tethered jailbreak? If so you need to put it in DFU mode and then use the redsnow option "just boot tether" under extras

Boot tethered using the redsnow or snow breeze which ever you used.

Like the others said, boot tethered you have to boot tethered EVERY time the phone reboots.
