Jailbreak / tether iPhone while on the go

April 4, 2010

Why:

You might be on the go and wanting to go ahead and get tethering to work, or to do some exploration of the jailbreak world. I found myself in a car, with wife driving, wanting to get tethering going so I could work on my laptop. The iphone has internet, but laptop does not.

Also these instructions can be used to get any internet-accessible file from your iphone to your computer.

The following instructions were done on a iphone of version 3.1.2, and mac OS X 10.6.2

What you need:

  1. iphone with internet access (can be 3g, 2g, or anything)
  2. mac or pc computer
  3. USB cable for iphone -> computer
  4. Willing to jailbreak your iphone (no other way to do it anywmore)

How to do it:

  1. Download the file to do a jailbreak
    • Download the free app ‘Downloads Lite’
    • Open ‘Downloads Lite’ app and browse to http://www.blackra1n.com
    • Download the file blackra1n.zip for PC or Mac Note: The download on this site did not work for me. I ended up googling for it and finding it elsewhere. It was like 500-600k in size.
  2. Get the file to your computer
    • Now we have to get this file to your computer. The ‘Downloads Lite’ program has a feature that lets it become a http or ftp server, if its on a wifi network.
    • On a mac, you can create your own wifi network. Basically, your computer acts as a wifi router.
    • To do this, click on the wifi icon in the upper right near the clock. It looks like a set of half circles.
    • Click ‘Create Network…’
    • Give your network any name, such as “MyMacBook”; set channel to “Automatic”; Hit OK
    • Go to your iphone Settings ‘Wi-Fi’ button
    • Select the network that you made above ex: “MyMacBook”
    • Open ‘Downloads Lite’ app and go to the ‘Settings’ section; Set ‘File Sharing’ to ON
    • Note the URL that looks something like “http://blah:8080”; It will have numbers instead of blah
    • Enter this URL into your computers web browser. I had to use Firefox, not safari.
    • Down the blackra1n.zip file to your computer, from the Downloads Lite interface.
  3. Jailbreak phone
    • You can verify the zip file on mac by using the command “unzip -l blackra1n.zip” If its good, you will see 8-10 files. If its bad, it will say it couldnt read it.
    • Unzip the file
    • Plug in iPhone with USB cable, into computer and phone
    • Quit iTunes or iPhoto if open
    • Run Blackra1n application
    • Click the single button in the program to start the jailbreak
    • Restart phone, as instructed; now you are jailbroken
  4. Get needed components
    • Open the Blackra1n app on your iphone
    • Have it install Cydia, the popular jailbreak app store
    • Run newly installed Cydia app
    • Go to Manage > Add a Repo source
    • Add http://apt.iphone-storage.de
    • Browse to the added repo, to see the applications that this repo provides
    • Browse down to the ‘T’ section and look for “Tethering 3G”; Install it
    • Restart iphone
  5. Install a mobileconfig
    • On your iPhone, go to http://www.iphone-notes.de/mobileconfig/ in Safari
    • Choose your country, and appropriate mobileconfig
    • Install the downloaded mobileconfig once given option
    • Restart iPhone once again
  6. Use tethering
    • Remember to turn off your custom network on your mac or pc. In fact, you wont need wifi on when you tether.
    • Assure that iPhone is plugged into USB -> computer Note: You can also do this all with bluetooth, but I have not tested this
    • On iPhone, go to Settings > General > Network > Tethering to turn tethering on
    • Mac should instantly detect a new network type. You can check this out in System Preferences > Network on a Mac
    • The new network entry for the iPhone should say that it is connected and list an IP address when clicked-on
  7. You are tethered! Browse to a webpage or open chat!

    Nice walk-through, going to have to try this on my sister’s iPhone or until I get an iPhone myself. Any thoughts on the next iPhone (the leaked v4 one)? Looks sleek. Would it come out on more than one carrier (ATT) this time?
