Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
Restart phone
If you are not jailbroken
Sherif Hashim discovered that you can activate your iPhone 4, iPhone 3GS or even iPhone 3G without the original carrier SIM card. You need a “phonebook sim card” or 02 simcard. You can buy these type of sim at radioshack, bestbuy or other mobile electronics store (for example here).
Once you get passed the Emergency Call screen, connect to Wifi, jailbreak using JailbreakMe.com and unlock using ultrasn0w. Once that is complete you should be passed activation and unlocked (able to use any sim). If you get a different simcard error, do the following final step:
Go to /private/var/root/Library/, delete original lockdown folder and put this lockdown folder after you extract it from the zip file
Restart phone
If you have itunes invalid response problem:
Connect to wifi and ssh to your phone (via winscp, putty, terminal, etc).
Navigate to your lockdown folder (/private/var/root/Library/).
Delete pair_records folder
Reconnect the cable and see that your invalid response problem is gone.
If you bought your iPhone 4 on ebay you will need the official sim (at&t) or a universal sim, like ones you can grab at bestbuy for $10 this will get you passed Emergency Screen.
One Apple fan published a video where he jailbreaks iPad by using his Nexus One’s mobile hotspot capabilities. Take a look at the video after the break:
Recently Vupen, which is a French security firm, posted an advisory that contained information about two critical security vulnerabilities in Apple’s iOS. After a while hacker comex used these flaws to create a jailbreak, which is now widely known and available on JailbreakMe.com.
But according to Reuters, yesterday Apple decided to react and its spokeswoman Natalie Harrison revealed that the company is currently investigating Vupen’s advisory. So it looks like these exploits are going to be fixed soon!
Jailbreaking an iPhone 4 is easy. Jailbreaking at an Apple retail store is fun. One of the users did that and captured everything on video. Take a look at the video:
FaceTime feature gives users the possibility to make voice calls. Apple restricted this feature to Wi-Fi only. Today it became possible to use it over 3G!
Here’s an interesting video from MuscleNerd, who jailbreaks an iPad using JailBreakMe in a plane (over New Mexico via “Gogo Inflight Internet” wifi). Nice!!
