Has anyone found any apps that are "location based" (for example, Google Maps, iWiki, AroundMe) that normally use the GPS function on an iPhone and allow you to manually enter in an address? I've read through a bunch of threads where people have tried to use the Wifi to determine the location, but as many others have found, it doesn't really work. I'm trying to use iWiki or AroundMe for when I'm travelling, but there doesn't seem to be any options for a manual address entry. It seems to make the program useless for a Touch if you can't use a manual addresss. Has anyone used either of these apps and can provide some insight into how to stop it from searching for a location via GPS or WiFi and allow a manual input of an address?
