A friend is going to go hiking the Pacific Crest trail, and needs a device that will use GPS to track her location, and post it up on a website (kind of like a journal). She was originally thinking about buying an iPhone 3GS, but the problem is, there is no AT&T service for large portions of the trail. Also, I don't know of any apps that would do this type of GPS reporting for her site. Also, it is none too durable for what the trail will endure. What can you guys recommend for a trip like this, as well as to be able to post journal entries to a website.
