3G not working in 3GS

[billybobr_06]

Hi Guys,

My sister (who lives in a different city than I do) is having some problems with her iphone 3gs (v3.0).

I jailbroke her 3gs a long time ago and everything has been working great. Recently, before taking a trip, i told her how to install ultrasn0w. She installed it, and rebooted after.

She was able to use a foreign sim card and everything appeared okay. Unfortunately, installing ultrasn0w has made her 3g and edge connections not work (data only)

She is able to make calls, and use wifi. But she cannot connect to anything in edge or 3g. She has tried restarting her phone, resetting her settings (network settings too), turning 3g and edge on and off. But nothing is working.

How can I help her?

Is there a way that she can restore from JB 3.0 to regular 3.0, cuz I dont want her to lose her ability to jailbreak by getting 3.1

Thanks for all of your help and for reading this

if she is using a 'foreign' sim card, she probably doesnt have the right APN settings for the data network...

Let me rephrase my problem

even when I use my regular carriers sim card the data no longer works. I've tried uninstalling ultrasn0w but the problem still persists

Guys,

Im begging for help

Without your help I will not have access to any data.
I know someone here can give me a hand.

Thanks again

mh, it's pretty strange. ultrasn0w normally doesn't cause things like that. I could imagine the sim swap causing it maybe.

the first thing to do would be going to settings > general > reset > reset networks settings.
but be aware that this will also erase any wifi password etc.

what you can do if that doesn't work is check your APN settings under settings > general > network > cellular data network
those APN settings should match those from your carrier (you can probably find them at their website, or you can give them a call).

the last resort - as always - is a restore through itunes. that should always do the trick.

I'm with Fido in Canada (Toronto)

To the other person above, this problem started before she even swapped the sim cards. It began right after she installed it.

Thanks for all of your help

here's what I could find:

          * APN: internet.fido.ca
          * Username: fido
          * Password: fido

Some users have had trouble configuring EDGE for their iPhone with Fido. Here are some tips that might help you along your way:

    * Call Fido’s Customer Service line and ask them to activate your EDGE account if you haven’t done so before
    * If EDGE still doesn’t work after that, call Fido and ask for a new SIM card. Many users have been able to get a replacement SIM free of charge (your number will stay the same)

these are the apn settings I guess :-)

I couldn't access it either until I installed a custom ipcc file.

yeah, I do, unfortunatly resolving this isn't that easy ...
you need to know how to SSH onto your phone and how to execute a comand line comand on the phone.
first of all install erica utilities from cydia.
then SSH onto your iphone and go to /private/var/mobile/Libraray/Carrier Bundle.bundle/
in their, execute
plutil -convert xml1 carrier.plist
after that, download the carrier.plist, open it, scroll all the way down. at the bottom there should be
</dict>
</pist>
ABOVE those lines, add:
<key>AllowEDGEEditing</key>
<true/>
save the file, upload it back to your phone, reboot, and "cellular data network" should be there.

Thanks.
A couple of questions though.

Should the edited plist read (at the very bottom):

<key>AllowEDGEEditing</key>
<true/></dict>
</pist>

And, should I upload it and replace it in the same spot where I got it?

I, personally, would put a newline before </dict>, but that's just a cosmetic thing

and yeah, upload it and replace the file on the iphone. if you want, you can backup your old file first, but it shouldn't be necessary I guess :-)
