Since the iPhone 4 jailbreaking tool JailbreakMe came back online after the US government ruling legalizing iPhone jailbreaking, their servers have been swamped with heavy traffic. The server went down recently after too many people tried to download the jailbreak file simultaneously. People are also experiencing crashes with the screen below showing.
Here are a couple of things you can try that might fix the situation:
- close the tab in safari, then close safari
- go to Settings > Safari > Clear Cache, Cookies and History
- Restart Safari
- This time go to JailbreakMe.Modmyi.Com
- Slide to Jailbreak
