iPhone 3GS bricked with error 23 after iTunes 9 and 3.1 firmware

I am not sure what the culprit was- whether it was iTunes 9, iPhone firmware 3.1, or a hardware issue on my 3GS. But Wednesday evening I installed iTunes 9 and firmware 3.1 with success on both. Thursday (yesterday), my iPhone functioned properly all day until about 3:30pm, when I took it out of my belt clip and it had an error saying it couldn't make or receive incoming calls, and that I should connect to iTunes and restore.
So, after connecting it to iTunes, it comes up with an error message saying "iTunes cannot activate your iPhone because the SIM card is not inserted or a SIM PIN is required". After checking the SIM card and trying again, I called Apple Support, and a nice man guided me through putting it into recovery mode (holding Home when connecting to the Mac), and restoring, only for it to come up with yet another error message, saying it can't restore "Error (23)". We tried downloading firmware 3.1 again and even trying on my other Macbook, to no avail. He therefore made an appointment for me at my local Apple Genius bar. It looks like I may have to swap to a new device if they can't sort it out.

Firstly, has anyone else had this issue since 3.1? This is the first time this has happened to me, and it seems too much of a coincidence that I have only just updated it. It is NOT jailbroken or hacked in any way, fyi.

Secondly, if I do have to swap to a new device, am I able to restore from the backup of my old device so I get to keep all my save data?

I had this happen with my 3GS almost a month ago. No amount of trying to restore would work and the Apple Genius claimed he had never seen anything like it.

My iPhone was bricked with the error 23. I plugged it into XCode and it failed to restore saying there was a radio failure. There was no 3G, no WiFi no edge and no bluetooth. They were all grayed out in settings. Apple replaced my phone with no problem. This is what you will end up having to do as well.

You will be able to restore from your previous backup.

Same problem. Was playing the iPod and had driven for a couple of hours using Maps.
It id get a bit warm so I switched on the air vents in the car that blow directly onto it in its holder.
Told me it could make or receive calls and needed a Restore.
Hasn't worked since, saying there is no SIM or it is SIM locked.

Should I visit Apple or O2?

Well I figured O2 would just blame Apples firmware, so I went straight to Apple, booking an appointment at the Genius bar. After a quick check and confirming it wouldn't restore even in recovery mode (hold the Home button while connecting to the computer) they immediately gave me a new iPhone instead. Went home, updated to 3.1, then restored from Backup so I didn't lose anything.

I got the same problem - can´t activate (says defect simcard) and can´t restore get code 23 in DFU mode and in Recoverymode it says defect simcard or locked sim.

Happen using my iPhone and Navigon today on a trip from Hamburg to Denmark.
Lost GSM-signal and then lost GPS-position, and got a message to connect iPhone to iTunes to restore it.

BUT I can´t do nothing....?

Bought the iPhone simunlocked from VODAFONE in Italy this summer...

Nice, and hope I´m getting mine replaced too....

Seems to me that theres a hardwarefault here somwhere? or is it overheating of the processor when navigating?

UPDATE:
Just talked to Vodafone One/Perugia/Italy - and they guided me through all the stages I allready have done - I told them that I got thesame No Service and error 23 in iTunes on two PC´s.

1. They said I had to go to a local/Denmark Appleshop - but here in Denmark they only sell iPhones through a teleprovider - so its a no go.
2. I then told them that I allready had shipped the iPhone to the Vodafone store - and they just said hmmm, thats the last option - YES but I have to try it out because I really need my iPhone working soon.
