What exactly do you mean you had to change your Sim card? Are you with T-Mobile and you asked for a new Sim card to replace your old one and it worked?

I don't think there is anything wrong with my T-Mobile sim card because when I put it into my old T-Mobile phone it works fine.

I have the same problem my phone was unlocked & activated with ziphone. Has worked fine for months then on Monday the dreaded no service. I have restored it & reunlocked & activated with ziphone, Liberty & winpwn & still no service . I am in the UK on Virgin the sim card works fine in my other phone.

I'm currently going through this and I cannot find a solution.
I have pretty much tried everything imaginable without any long term success.
Sometimes you think you've fixed the problem but the problem comes back within a day or two max.

I am noticing more and more people running into this situation. But it seems that no one (yet) has a fix.

The problem is so intermittent that it is really hard to troubleshoot, I still cannot tell if it is a hardware or software problem.

My latest effort has been to buy an ATT PrePaid Sim card and while I thought it solved my problem (by working for a full day) it now too has stopped working. Now it shows 'No Service' for most of the day with maybe a couple good hours here and there!

I will continue to post anything I come up with. Going try put in the wife's ATT sim card now (she has an iPhone through ATT the legal way).

I just finished trying the wife's ATT sim (legal iPhone sim) and it started off with a strong 5 bar signal then maybe 10 minutes later I go the dreaded 'No Service'.

So I am going to virginize and put in her sim again and see what happens. If it fails on me again then it's time to make an appt at the Genius Bar!

same problem unlocked now have 2.0.2 version with tmobile sim and no service but when i add to my blackberry phone sim works fine and i have service

hmm, just wanna to share this. I had replaced the signal cable after the iphone started showing no service or very poor in signal. After the replacement, the signal is back to normal and no more NO SERVICE on the iphone. My view is this issue hardware problem than software problem.
