Hi folks, 2 questions for you - much obliged to anyone who can help: 1. I want to make sure i don't incur the insane costs of data use in the US when i head out there in September. How do i ensure i can use GPS so that i can use Google Maps/Navigation without incurring data transfer costs? I used to be able to do this with CoPilot on my old XDA but not sure how to do this on the Desire 2. I get 75 picture messages free each month (which i was told includes sending them from abroad to a UK number), however, when i tried to send MMSs a bunch of times while in the US last month to UK numbers, everytime i got an error message saying "Unable to send". I tried to send it with both wifi on (connected to a home network) and also with wifi off. I didn't turn on Mobile data (mainly because i assumed i would be charged for the data), but it appears i have to have Mobile data transfer on (having now sent a bunch in the UK to friends here). My qyestion is - do i need Mobile data on to send MMSs in general, and if so, will the associated data transfer costs when i send MMSs to UK mobiles from the US be covered in the free 75 picture messages i get each month? Many thanks!
