I've got a Spanish Trinity and also made a question about the GPS ROM update to HTC, here is the answer:
Thank you for your enquiry concerning the HTC P3600 mobile device.
The HTC P3600 currently does not offer GPS Functionality. There is a possibility of an update to enable the GPS functions of the device at a future date, and we hope to be able to do this as soon as possible, but we cannot and do not guarantee this.? If you buy the P3600 for possible future GPS functionality, you do so entirely at your own risk.
I hope we have it shortly but I've got my doubts!!!
