Question [Q] UK HTC Sensation XE - GPS problem in US

Hello, I purchased an HTC Sensation XE and found out that it is a UK version.

I am not able to get a GPS lock and I think it is because the US does not use the same GPS protocol as those satellites used in Europe.

Does anyone know if it is possible to root this phone and install new flash firmware to make it work or is there a hardware difference that will make this impossible?
