My tilt isn't recognizing the sim card?

[heyitsreg]

So I've had my tilt since May 2008, with no problems ever. Today my phone said I had no service then after a little while it said the sim card is missing. I have reset my phone multiple times and reinserted my sim card multiple times, making sure the latch was secure and it clicked twice. It still is saying it's missing. I placed my sim card into another phone and it worked fine. I then took the sim card from that phone and put it in mine and it didn't work. What can be the issue? I have a feeling it has to do with the phone.

I had the same problem and i found no answers. if you turn the phone on when it is slid open, it should work, just dont close it again or you will get that insert sim card message. but after awhile, that stopped working for me. I recommend getting a new phone.
