Owners of the Samsung Conquer 4G on Sprint may have received notification of a small OTA update this morning that brings a couple of little changes to the device, including a "security fix." Like with past updates, that basically translates into "removal of Carrier IQ software."
Aside from that, it also removes the Magic, Smoke, Maps, Nexus, Spectrum, Water, and Waveform live wallpapers (does anyone actually use those, anyway?). The update should be rolling out now according to Sprint's online documentation and will hit all devices within the next ten days.
If you just can't wait to grab the update, however, you should be able to pull it now in Settings > About phone > System updates.
