Hi - I've been looking for a clear answer to this, and while a number of people have posted about it, I still am not 100% sure of the answer. I am going on a trip to England in a couple of weeks; I am not planning on using my phone to make calls or send texts while I am there, so I am not looking into any kind of international data plan (I'm not even sure if this exists for Eris). However, I will be driving around quite a bit, and it would be really nice if there was any way to use the GPS navigation. From other posts it seems like this may not be possible, but I'm not sure. I had thought that since GPS uses a satellite signal rather than the cell network, I could put the phone into airplane mode, then just enable satellite reception and I would be all set. Perhaps this doesn't work because the data connection is needed to load the maps ... ? Anyway, if someone could explain to me the ins, outs and possibilities of using GPS in other countries, I'd much appreciate it.
