How do I enable Wifi Hotspot / Tethering in an iPhone 4 or iPhone 3G?

Non Jail Broken iPhone

1) With AT&T and Verizon, you need to purchase a tethering plan. The Dataplan is : DataPro 4GB which costs $45 for 4 GB. If you finish off using the 4GB then you can get 1 GB for $10.

2) Turn on the Wifi tethering in the following sequence

Setting--> General--> Network--> Setup internet tethering

You can choose Bluetooth, Wifi or USB tethering.

Important Update : iOS has officially disabled Wifi tethering via a Software update. The reason might be probably that the device gets heated up a lot while behaving like a Wifi tethering device.

Jail Broken iPhone

The only way left for a official Wifi tethering (without datacable or other tethering) is by following the Jailbroken way..

Method

1) Tap on the "Cydia" icon on the homescreen.

2) In the search bar, type "MyWi". There will be 2 apps displayed. Select the app that does not have "No Rock" next to it.

3) Tap on "install" and then confirm the installation.

4) After the installation is over, tap on "Reload SpringBoard"

5) Launch the App. The app will look like below.

6) Turn on Wifi tethering. Enter an access point and an (optional) password. And Voila, you're ready to use it.

PS : Sometimes, the application doesn't launch properly. You might have to restart your mobile iphone if in case the app hands.

I am unable to share 3G data via Wifi tethering / Hotspot. What should I do?

Ans : Resetting network setting solved the problem for me. Settings --> General --> Reset --> Reset Network Settings. Reboot the iPhone if need be.

Limera1n vs Greenpois0n vs PwnageTool

There are too many digit embedded iPhone jailbreaking tools and the uninitiated guys are definitely ought to get confused.. Limera1n, Greenpois0n, Blackra1n, PurpleSn0w, RedSn0w.. Sheesh, quite a few..

In this post, I am going to post about 3 of the popular tools, the Greenpois0n, the Limera1n and PwnageTool

PwnageTool

PwnageTool is the first ever iPhone jailbreaking tool that was developed by a group called iPhone Dev Team. What started as a iPhone only jailbreaking tool has now diversified into iPod Touch, iPad and Apple TV too.

PwnageTool works only with the MAC OS.. The Windows users cannot use PwnageTool. There was a tool called WinPwn but the development was stopped due to the lack of interest..

The latest version of of PwnageTool is 4.3.2. PwnageTool 4.3.2 jailbreaks iOS 4.3.1 for iPhone 3GS, iPhone 4 (GSM), iPod Touch 3G, iPod Touch 4G, iPad, and Apple TV 2G. Basically, it jailbreaks everything except the iPad 2.

Disadvantages : Not a tool for Windows Users..

Tethered or Untethered : Untethered

Greenpois0n

This is a tool by Chronic Dev Team which is used to jailbreak all iOS devices, the latest being for the firmware 4.2.6 of the iOS.

Initially developed as an exploit by p0sixninja of the Chronic Dev Team, the Greenpois0n was to exploit a low-level bootrom exploit called SHAtter discovered by pod2g for iOS4 devices which is supposed to pwn all supported iOS devices for life. The claim is this exploit can’t be patched by a simple firmware update by Apple . This would require a revised version for the hardware of iOS devices in order to patch the loophole.

Sounds WOW right??

But just before the launch of Greenpois0n, George Hotz, the GeoHot, came back from retirement and released Limera1n, another jailbreaking technique (Discussed below).

So the Chronic Dev Team delayed their launch of Greenpois0n and used the Limera1n exploit for the Greenpois0n tool giving the reason that releasing the original SHAtter-based Greenpois0n would be "a complete waste of a perfectly good bootrom hole in light of Limera1n, and so it can be held until Apple closes Limera1n’s hole."

Latest Release : The latest Greenpois0n release is Greenpois0n RC6.1 which supports iPhone 3GS, iPhone 4 GSM & CDMA, iPod Touch 2G, 3G, 4G, iPad, Apple TV 2G. Basically, everything except the iPad 2 (as on 2nd May 2011)

Tethered or Untethered : Untethered

Limera1n

Geohot, or George Hotz, a American Hacker, known for hacking Sony PlayStation3 (and was sued by Sony), released this iOS jailbreaking tool called Limera1n.

History

In April 2010, GeoHot announces Limera1n, a all device jailbreaking tool. After a lot of hype and expectations, GeoHot announced his retirement from the jailbreaking scene on July 13, 2010. This led to the speculation that Limera1n was all hype and no worth.

He came out of his retirement, on October 9, 2010, just before the Chronic Dev team scheduled to launch Greenpois0n and launched Limera1n. It was initially a Windows only tool, he launched the Mac OSX tool on October 14, 2010.

Current Version :RC1b

Tethered or Untethered : Untethered
