Ah, the smell of a fresh OS!

Being on the shady side, I have to operate an Unlocked Jailbroken iPhone.

It's awesome, really; but there's always a catch. After upgrading to iPhone OS 4, I realized that I cannot set my "Mobile Internet" data.

What I mean is the tab for Cellular Data Network was gone, it had vanished!! There I was, offline in this omni-connected world.

After some thorough Googling, though, I found an awesome solution to my problem.

All you have to do is connect to some WiFi on your iPhone, go to http://www.unlockit.co.nz/ follow some simple instructions and enter your APN data in the nice form there.

Select the Email Profile option (the other one won't work) and wait.

Open the attachment from the email, confirm and you're done.

Enjoy you new connected iPhone!
