Hi All,

Okay I had purchased my 3G Unlocking TubroSim from ebay item # 300280726909.

It worked fine fore like 3 or 4 days, and today all of a sudden it just stopped working.

I was doing this, I was watching a video, then shut off my phone. Video stopped, but I pressed the button on headset and it just played the voice of video.

That's what I was doing last thing.. I don't know if that caused it to not work or not..

All it says now is "No Service" in the top left corner.

My iPhone 3G isn't Jailbreak, it was activated using AT&T simcard, so I never jailbreaked it.
