(keitai-l) Re: WCDMA and CDMA 2000 in the same phone

Yeah I'd rather carry one slim W-CDMA handset and one slim CDMA2000
handset instead of a single big, bulky W-CDMA/CDMA2000 handset whose
battery only lasts less than a day.. But I wish I could use a single
SIM card interchangeably for both handsets. Are CDMA2000's RUIM and
W-CDMA's USIM compatible?
