I finally just updated my phone to 2.1 the other day, and I just now jail broke it again. But I accidentally did the simple version on pwnage tool the first time. And don't want the pineapple on the startup screen, so I restored it, and again jail broke it but this time with no custom boot logos. Now my phone service seems to be gone! any ideas. I restarted it. I sync'ned it with my computer. Everything seems normal. Just no signal. At all. Help?
