Sanyo 8100 ringtone error

I just got my dad's old Sanyo 8100 (he got a new 8200) and my friend told me of a site (3gforfree.com) that I can download unlimited ringtones/screensavers/games for free from. I downloaded 5 songs and I have 5 games already on the phone. I have 103kb left and the song takes up 23kb (i know this because my dad has the same song, Jimi Hendrix - Voodoo Child). When I go to download it I get an error that says that I have insufficient memory. What is the problem here? And how can I fix it, can I delete the ringtones that came with the phone anyway, considering I don't use them?

I know this isn't going to help, but I am having the same problem and would also like to know how to remedy this. I have over 200kb of free space, and it says that I cannot download because the memory is full. I've deleted files to make space, and it still says that the there is no space. I've been charged for the files, but can actually get them . I don't know this works on the boards, bump, hopefully it does because I want to get this problem solved. The sprint stores in the area are of no help, the employees just try to badger you into getting a diagnostic on your phone and then telling you that you need a new one.

So, anyone, help...please?
