I recently picked up a Sanyo 8300 to replace my Samsung 660 which broke in half after 2 yrs of hard core use (ive always had a Samsung) anyway, Im tryin to customize this phone (for free of course!). Ive tried a few sites-fun for mobile.com-how do I get the tones on my phone. Ive tried texting the link but my phone reads "unable to view page" when I try to connect. Any advice? Im just not inclined to make my own ringers. Hook me up y'all!
