"No Sim Card" issue - Sim present

---

Hi XDA,

I recently re-encountered a problem with my N1, not sure if any body else has, is where the phone doesn't detect your SIM suddenly, giving a "No SIM Card" error, when it was working fine moments agos, after sleeping and waking the phone when i wanted to use it later. Then further reboots only result directly in a no sim error.

Before it happened before reflashing the radio fixed it, but it has suddenly come back today and i've tried everything from 03 -> 06 radios, and CM5.0.6 -> .8 Test5 and still the issue is present, where it no longer detects my SIM.

My SIM works in other phones around the house, and all the other SIMs ive borrowed to test all come up as not detected.

I am in Australia so it would be a PAIN to RMA with HTC, tho i would be in the states for 2 weeks soon so maybe if it is eligible for warranty im not sure.

Has anyone encountered these problems and what were your solutions?
