So here's how it can be done:
1) Perform a selective backup with Desktop Manager, saving only Content Space from your real Blackberry, then disconnect
2) Download/Install the Blackberry JDE
3) Start the MDS Simulator
4) Start the BB Simulator (probably best to choose your specific model)
5) Simulate a USB connection
6) Restore the back up from 1) to the simulated BB
7) Surf to the web site that has your ringtone and save it to the simulated BB
8) Perform a selective backup with Desktop Manager, saving only Content Space from the simulated BB
9) Disconnect/Close the simulated BB
10) Connect your real BB
11) Use Desktop Manager to perform a selected restore of the saved Content Space
12) Go to Profiles>Show Tone and find your new content!
I can't promise this'll work for everyone as I've only tried it with my 7100g, but I can't see a reason it wouldn't work. I suspect it also works as a way to get images onto a BB without a data plan as well.
原理挺简单，但过程很繁琐。 将BB的CONTENT STORE（铃音，图片等都存在这里）单独备份出来，导入BB的桌面模拟器，用模拟器上网下载图片，铃音，再对模拟器的CONTENT STORE（内有已经下载的图片，铃音）进行单独备份，最后导入BB就可以了。
桌面需要安装：
－BB JDE
－模拟器（针对手里机器的型号）
－MDS模拟器（没有它，BB模拟器就不能上网）
以上软件在BB的老家都有下载：
