Hi,
Apologies for a new thread with a newbie question, have had my Hero for a couple of weeks, but work meant haven't had a chance to play with it properly yet. I'm going to the US tomorrow, and don't want to incur any roaming/mobile internet etc charges (i'm with Tmobile), but was wondering whether I can use the GoogleMaps app and not incur any charges? It'd stop me checking the map of where I ended up on my wanders.
I appreciate the answer may be a bit obvious, but halfway through my packing and hoping someone can just tell me what i need to know. Thanks.
