The LG Optimus Black is one of LG's highest quality phone, and after a few FCC fillings were discovered, it might be going to more carriers than expected. We've known for some time now that this bad boy would be going to US Cellular later this year. After the names of the FCC device were decoded, we can now add sprint along with other US carriars to the list.
This was discovered and decoded by the guys at Pocketnow, who managed to figure out the name US855 meant US Cellular while LS855 meant Sprint, As855 meaning Alltel, and VM855 is going to Virgin Mobile.
