I don't know about the rest of you guys. But I will chalk this up to professional courtesy

The new 3G chips ( the white/blue ones) have been having problems in the 417. Use the the White/orange stripe chips instead.

You might get folks complaining of the phone saying...CHECK SIM/INVALID SIM quite often
dropping calls, or missing calls as a result

It is not the phone, but the chip itself

I know our store had done like a dozen exchangews before we figured it out

My wife and I have been having this problem with our 417 with Cingular. The message appears 2 or 3 times a day to replace the sim card. Does anybody have a solution?

kakpadzi: Is your SIM card white with a blue stripe? If you are still having this problem I would go to a Cingular store and ask them to replace your SIM card (with a SIM card that has an orange stripe). Good luck.

Unfortunately Cingular no longer carries the sim cards needed for any C-417 having 3G network issues. The only thing you can really do is replace your phone under your warranty until you get one that works. also, it's not worth getting a different make and model, the only phns they can offer either don't have a camera, don't have bluetooth, or both.
