I've found a really cute and unique Doraemon cellphone on Ebay Taiwan, I really wanna buy it. Well, it's not a smartphone or such like that, it's just a regular one and has GSM 900/1800. I know that in order to use a phone here, we need gsm 1900. I'm wondering whether anyway i can add the gsm, upgrade, fix or whatever to use that cellphone in america. Plzzzzzzzzzz help!!!!!!!! Thanks a lot! ;-))
