check bihar the device didn't get accidentally set to 2g & if not then you might need a new SIM Card because it could be fried.

How is it surprising? Koodo runs on the 3G network and the iPhone 3G/S has those compatibilities. The only issue is that it needs to be unlocked and the APN settings need to be correct.

Wrong.

It has been stated by Koodo that the Iphone3G will not work on their network. There have been instances where the Iphone3G MAY work, but the official word is that the Iphone3G will not work on Koodo's network. That's why it's a surprise.

Data on an Iphone3G WILL NOT WORK under any circumstance because there is no way to program the APN into the phone. Iphone3GS and above is done via itunes. There are no Apple apn settings that can be programmed manually into the phone.

Yes there is a way to APN the phone.

You simply pick the APN you need and it will be added to your phone.

You have to access the site on an iPhone to see the correct page with the options. Unless you can change the user agent on your browser to fake an iPhone but I doubt that.

Try putting the sim card into another phone. If it still gives a sim error the card could be burnt and you may need a new one.

Are you sure the phone is factory unlocked? Not the hardware sim faker unlock method. That potentially has issues with the firmware for the most part and also apple locks up those exploits with every update.

Could also take out the sim card and try cleaning the contacts a bit, and putting the sim back in. Apple doesn't say this but it is best to give your phone a reboot when you take out the sim and put it back in.

Just hold the lock and the home button until you see the power off and keep holding until it completely goes black.

If all else in this topic fails the other possible explanation is the contacts in your phone are damaged, I've seen phones where one of the sim reader contacts has fallen out. In this case you're probably best off getting a new device, rather than trying to fix it.
