Having trouble using JailbreakMe.com? Try restoring your iPhone
This is the lovely screen I saw a good nine or ten times yesterday afternoon. I had tried clearing my Safari cache, checking back every 15 minutes, killing and restarting Safari in the multitasking bar, and making a little Steve Jobs voodoo doll out of a bar of soap. None of that stuff worked, and all I saw was Safari crashing to the home screen right after the words “Sit tight.” appeared on screen.
Then my best pal texted me and suggested that I restore the iPhone, and that turned out to be the key. I had previously jailbroken using PwnageTool, and something about that process apparently interfered with JailbreakMe.com (despite the fact that I was back on stock 4.0.1).
So if your Safari Mobile has been crashing when trying to use Jailbreakme.com (or the mirror at Jailbreakme.Modmyi.com), restore your iPhone through iTunes, jailbreak your device through the website, and then sync all of your content back to your phone. That’s what worked for me.
i had incounter it just this day, all i did is just simply sync first my iphone or ipod touch on itunes, ver 9.2, and thats it, i jailbreak my iphone easyly!
