Hello everyone.

Could someone please help me out.
I am currently on 2.2.1 with 02.28.00.
I would like to upgrade to 3.0.1.
Now here is the question:
Can I upgrade and still keep the 02.28.00 to have it unlocked for any SIM card or would it become locked again???
I have heard that someone upgraded the 02.28.00 to 4. something and then used ultrasn0w 0.9, would this work?

How should i go around this one?

Thanks in advance.

Henius.

Hi all.

I have almost the same problem as Sara here.
I HAVE had my 3G 2.2.1 Modem2.30.03 jailbroken BUT it still says Invalid SIM when I try to put my Orange UK SIM in.
I installed Cydia but don’t know how to use it???

Is there anyone that could explain to me (as if I was a retard) how to unlock my 3G 2.2.1 to work with any SIM card.

I do not have a o2 SIM card to put in the phone.

I would be VERY VERY greatfull if someone could help me with this…

Thanks in advance.

Hello,

I upgraded my G2 iPhone to OS 3 today, but could not get the internet to work.

I used pwnagetool_3.0 to jail brake and unlock it, but still no access to the internet.

Is there one or more apps I need to install from Cydia that will allow me activate the cellular data network?

Thanks in advance for any help you can provide.
