I get something that pops up saying I have to install itunes and then it makes me register the iphone in itunes?...i guess mine doesn't work

[Username00089]

I'm on T-Mo US, and I can't get this to work. I added the profile, but keep getting the "Could not activate cellular data network" error. any idea?

Settings -> General -> Network -> Cellular Data Network ->APN and put in epc.tmobile.com

Install iTunes on your PC. That's the desktop manager for iPhones.

If you have a new phone and need it to be registered all you need
is to put an AT&T sim card in the phone for a moment until iTunes
registers the phone.

[LHEFT]

I have an account already with AT&T...I installed itunes but the phone still says to plug into it and it only allows emergency use.

So when you connect your USB to your computer and open iTunes nothing
happens?

[LHEFT]

Nothing happens.
I open itunes and I made itunes sync with the phone and the phone still tells me to hook to itunes.
I thought I would be able to plug in the sim and run with it after th APN change

[Username00089]

So you're saying that when you hook the phone to iTunes with the sim card in
the phone it won't let you register the phone at all? You're still able to sync the
phone though?

[LHEFT]

yes. No register and the phone can sync

Do I have to register the phone? I'm already with a provider.

it is as if the iphone doesn't recognize the sim?

[Username00089]

Yeah that's what it's sounding like. Do you have an old att sim card lying
around? I had some trouble once with registering and I used an old ATT
sim card that I had and it registered it quickly.

[LHEFT]

I'll try that thanks.

[LHEFT]

The old sim didn't work either. I can't figure this out.

[Username00089]

Is this a 3GS or 3G?

[LHEFT]

I believe it is a 3G but possible a 2G? Does it matter if the APN is changed?

[Username00089]

What color is the back?

[LHEFT]

black on the back and silver

[Username00089]

It's a 2G iphone then. Delete the APN profile from the settings. I believe it's
settings>general and you should see it somewhere there and can be uninstalled.

[LHEFT]

so I can't do it?

[Username00089]

Yeah you can do it but I don't know why it's giving your problems to register the
phone. Let me get someone in here that knows more about this than I do.

My friend is using is unlocked iphone on his tmo bb plan...

Does the 3G work with TMobile/BB data plan? I'm think of buying a iphone off of EBay and unlocking it.

[Username00089]

No because the iPhone has a 3G radio compatible with only att's 3G bands

[SoxfaninFL]

Ok thanks. That sucks!

[UrbanAdolescent]

Thanks, I used this on an iPhone 3G that I got my hands on and it works.

[Karivalis]

Please respond -
Every time I try to do this it works, but it takes me to the activation screen on the iPhone with my blackberry bold 9000's SIM card. Do I have to pay for the activation fee?
Does anyone know a way around this? I'm on a 2G iPhone with the newest firmware.

[Username00089]

When you have it connected to itunes while on the activation screen and put your
sim card in there it still doesn't activate? For whatever reason this seems to be a
problem for 2G iphones. You'll see on the page before someone is having the same
problem but I really am at a loss for a solution to this.

[Captain Marvelous]

Can I do this same procedure if I have a sidekick plan?
