yes from cheapy internet mobile phone accessory places, basically you put a chip/simcard thing into the sim card holder behind your battery pack, and the back you get holds the two sim cards. you switch between them with a button on the back. better hope your phone isnt of the jazzy cover variety, as im sure the covers come in blue or black. lol

cheers 4 that, i thought u could get em some were
ps just a grey cover, no jazszy cover 4 me lol
