Ok I jail broke using redsnow and I got through all the steps and it went to this screen that looks like a harddrive with a green arrow pointing down and a spinning pin wheel at the bottom. It has been on this screen for awhile now and I was wondering if it is supposed to take this long. Please get back to me.
make sure to use redsnow 7.2 (the one i used) or if 8.0 is out, use that. it should tell you version in the .exe name and the first page upon opening it.
