Could this be a hardware issue?

[johnnylovescookies]

So i recently was on Iphone OS 4 beta 4,
And now I downgraded back to 3.1.3 so i could unlock my phone.

Im on firmware 3.1.3 with baseband 5.13.04 and they said the unlock works for this baseband.

So i jailbroke 3.1.3,
took out my sim,
Ran the new ultrasnow 0.93 to unlock,
and put in my sim after it rebooted.


When I put in my sim,
the dot comes over the phone and the phone makes the sound of getting a new voicemail.
And it pulls up my number in the "Phone" settings.

Before I ran ultrasnow,
It the phone settings,
it said unknown in the "my number" field.

And my wifi works correctly,
But still it continues to say no service.
Ive tried with 3 different sims.

2 centennial,
and 1 T Mobile.

and yes,
my 3g is off

EDIT:
I can confirm this is a hardware problem,
Because i took my phone apart,
and disconnected my antenna ribbon cable.

I put it back together,
And tried to get service and I got the same exact results as when the antenna was plugged in.

Now i gotta convince my mom to order me this part:

feel free!
