Ok, I went through Pwnage to upgrade and followed essentially every directions I found online to the "T". The result, everything works and JB'd iOS4 but Cydia would crash. It just goes back to the Springboard. I have tried JB'd/Pwng again 3 times already and I don't know what I'm doing wrong. Finally, based on one solution I found which is really a workaround is going "SIMPLE" mode and let PWNAGE do everything itself which means having the Pineapple logo, etc. Cydia here works. So...I really don't want to have to stick to these logos but I do want my JB. Any suggestions and yes I have tried deleting "files" that is supposedly in the update folders and what not but this is a fresh installation and nothing is in there.
