Hi, All i have a 3g 8G legit vodafone egypt i was running 2.2 then i restored to 3.0 as instructed and used redsn0w everything was running smooth except for battery drainage i was told to restore again but as new phone to get rid of old backup data from 2.2 that's causing the problem, i did so and i activated through itunes legally before jailbreaking (i'm not even using ultrasn0w, and did not install it) since then i installed APN editing but strangely i can't find it in my setting/general/network although it was there before i restored as new phone.
any one has an explanation for this

there is a package in cydia that will show the cellular data network.

launch cydia and look for "APN Editing."

what happens is that if you're on a legit plan and doing everything Apple wants you to do (except the redsn0w part), the cellular data network is hidden because your phone is locked. Apple has carrier and APN settings for every official carrier already in the OS, and will use them automatically when you insert an official SIM.

Once you unlock it through ultrasn0w or legitimately, the Cellular Data Network will be shown since you could be using a carrier Apple doesn't support and doesn't have their APN settings (the biggest example is T-Mobile USA).

I can try to answer your iPhone related questions! follow me at @acwan on twitter!

do you really care, or do you just need to change your APN settings???

Take your iphone's safari to here: unlockit.co.nz

actually i installed this package and i was using it on 2.2 but when i installed it on 3 it won't show and i don't get the cellular data network option on my setting

"APN Editing" app in Cydia does not work for 3.0. Apple changed the directory path where the file to show APN needs to be overwritten.

I have a legitimately unlocked Vodafone AU iphone using a Vodafone SIM. The APN is still hidden cause the vfoneAU plist file disables this menu when a Vodafone AU SIM is inserted. This will not change with any unlock method, legit or not.

"unlockit.co.nz" works... but if you're out and about, you will not be able to enable / disable cellular data again until you're in a wifi area.

I need to edit my APN to enable / disable cellular data. I don't want my iPhone to use data when I don't want it to since i'm charged $1 per 5 minute block. Which means even if I get any notification (new emails, new updates in app store... etc) I get charged $1.

OK, I've found a more permanent solution that works. Basically this is what the "APNEditing" app in Cydia supposed to do

A post from pattulus of modmyi forums:

I used a little application called "pledit" for windows to edit the plist file and used "winscp" to SSH. Don't forget you'll need to install "OpenSSH" from Cydia first.

Also make a copy of the original plist file just in case anything goes wrong.

I don't have to put up with unecessary data charges anymore!

Hello,

I 've tried but It don't work. How can I sure that I'm editting the right file.
