The problem isn't in making a multi-band phone, but rather having the hardware needed to REJECT out-of-band signals and channels particularly when channels are spaced too tightly, without sufficient "guard bands". It means adding expensive and possibly bulky filters to the RF section and may even impact radio sensitivity. All in all, the 700Mhz allocations are a big mess.
