same thing happened to mine.. i just unplugged the phone and went through the redsnow process again... and did the part where you hold down power and home more accurate ... i guess i rushed it the first time and had me on that screen forever. now it works fine.
How to you put it in recovery mode? Did you just hold the home button with the usb cable unplugged and then kept hold of the home button while plugging it into the computer till the iTunes logo appeared?
Or did you do it by holding the power button and home button then releasing the power button and keeping hold of the home button.
