I live in an apartment behind my landlord's house, where the router is. My macbook gets a wifi signal (albeit a relatively weak one most of the time), but my iphone 3g gets no signal at all. So, is the wifi antenna in the iphone weaker than in the macbook, or are there some settings I can alter on the iphone to get it to pick up the network? Sorry if this is a newb question, but this is my first iphone. Thanks in advance.
