"I purchased an unlocked TYTN II a couple of weeks ago in the US and brought it to Mexico (where I live). I put my SIM card (Telcel) and started to configure my phone. However when the configuration screen asked me to select the country where my cellular operator is, Mexico is not included in HTCs list. As such, I am having compatibility issues. I strongly suspect that my TYTN II is the European version, does anyone know if I can install the North American operating/installation system in my phone? If so how? And, will this potentially eliminate my compatibility issue? (North American versions generally have Mexico included). If not, does anyone have a potential solution? Many thanks!"
