Hey guys I just jailbroke my new Iphone 3GS and had no problems with any apps until I downloaded Winterboard. I was asked to reboot my phone and it then shut off. Now every time I go to turn my phone on, the black screen with white apple logo appears as usual, but then my phone shuts off again. I was wondering if there is anything I can do to get my phone on to either fix the problem or uninstall the app???

Recovery mode + Restore. Maybe there is an other way but ...

Download iPhoneBrowser. All you need is the device to be plugged into the computer via USB.

iphonebrowser - Google Code

Then access the iPhone files and SSH to "/private/var/stash/Applications.xxxxxx". From there I would download Winterboard.app to the computer just in case, as a backup. Then delete the folder Winterboard.app on the phone.

^ you, I would do as the "Wizard" Neo says.

Thanks Neo but I'm still running into problems. I downloaded the iPhoneBrowser and plugged my iPhone into the computer, but because my phone won't go past the apple logo before shutting off again, the software did not recognize that it was connected. Thus it did not display any of the files that are on my phone. Is there something that I am doing wrong here or am I just screwed?

I would say DFU Mode and restore. If you can't access the files then there really isn't anything that you can do. Sorry

Don't know if this would work...but if I pop the sim card from my 1st gen iPhone into my 3GS, can I at least get the phone to turn on and then go from there?

Try holding down power and home until the phone shuts off. Then pull out the sim card.

I just had the same problem after jailbreaking my friends 3gs. Any way around this? he doesnt want to restore due to losing some information from not recently syncing..
