pandemic nailed the name of the Sidekick 3 MP3 player in only the 2nd comment. That’s right, according to the manual the MP3 player on the Sidekick 3 is named SonicBOOM. Based on the manual page we obtained, it’s no surprise that the miniSD card is going to function as the storage for your MP3s, and will show up as a removable drive on your PC. Luckily no extra software, or DRM codecs or anything to install. Just copy the MP3s over, unplug, and play! With the recent release of 2GB miniSD cards (which the Sidekick 3 can hopefully handle), you’ll be able to carry approximately 500 MP3s. And if you downsample the MP3s, you’ll be able to squeeze even more on there. Just don’t forget to leave some room for pictures taken with your 1.3megapizel camera. Looks like Danger is really listening to one of the top demands users had after the Sidekick II came out!
