Unlocked iphone 2.2 on t-mobile suddenly gets "no service"?

[yugosakimi]

Hi,

I have an iphone 4gb that I restored, then re-unlocked with firmware v. 2.2. It's on a t-mobile network, and it was working fine for a few days - working with itunes, etc.

Then a couple of days ago it lost reception completely, displaying a "no service" message all day, even in places it would normally get full reception. No calls, no texts, nothing. I tried a few things, like putting the sim into a regular t-mobile phone (it got reception) and putting it back into the iphone - i shut it off and restarted a few times, nothing seemed to work.

It got a signal yesterday, and was working fine until this afternoon, but then it lost it yet again. Has anyone had this problem? Any advice would be much appreciated.

I would do another restore and re-unlock.

But, it could also be a hardware failure.

What is padding a sim? I've never heard of it...

Aha. Thought about it too hard.

restore and unlock again is the backup option. anyone who's found another method, LMK

Sometimes it is needed.

Did you get it working?
