Firmware 3.1.3 - Internet Tethering with Factory Unlocked iPhone
I have an oficial unlocked iPhone which I just updated to the new firmware 3.1.3. I have read rumors on the web that with this new firmware oficial unlocked iPhones can use the Internet Tethering option on the phone with unoficial carriers. However, I have checked Cellular Data on the phone and the spaces to add the APN for tethering is not there. Also, there is no option for tethering on the Network. So basically my iPhone is not showing signs of allowing tethering after this firmware update. Does anyone know if this is true?
I live in Costa Rica and the telecom provider here does not carry the iPhone but it does support tethering. It would be great if I could take advantage of this without having to jailbreak.
Thanks for your help in advance.
