i have had the Sanyo, 6400, 4900, 4920, 7300, and 6100 and all have been capable of downloading images and ringers form sites such as mbuzzy.com and 3gupload.com. usually they are saved in the screen savers folder with the down directional. i have tried this many times with my 4930 and nothing shows up. NOT a new download icon, nothing inthe screen savers folder, or event he new my content folder.
I recently got my wife the same phone, and had a similar problem. WHen ever she tried to download a picture from mbuzzy it would just open the picture in a web browser window instead of doanloading it. Write to mbuzzy and explainthe problem. It has sonmething to do with their web site...NOT the phone. THey made achange and wrote her back. Now it works! DOn't waste your time calling sprint either. THey no nothing!
