Nope - you would need a quad band handset. The UK uses frequency bands 900 & 2100 MHz - whereas america uses frequency bands 850, 1700 & 1900 MHz.
In IT field, dual band is associated with the wireless router. This router handles frequency bands of 802.11. Dual band routers support 11a users in 5GHz band and 11b/g users on the band of 2.4GHz.

No - the phone has one operating system. The 'dual SIM' system allows the user to have two numbers allocated to the same handset.
Unlike ordinary routers that only support one wireless signal band, dual-band routers contain two different types of wireless radios. When first introduced many years ago, dual-band routers supported both 802.11a and 802.11b

It's not necessary to have both SIM cards installed if you don't need them. Dual-SIM is simply an option to have two phone numbers for one handset.
In telecommunications, the terms multi-band, dual-band, tri-band, quad-band and penta-band refer to a device (especially a mobile phone)
A dual band wireless router is the most modern type of router. It broadcasts over two bands, so it is faster and more reliable than a single band router.
Apparently you can have just one sim card even if the phone is dual sim compatible.EDIT: 'Dual SIM' - simply gives the user the option to use two different numbers in one handset. It's a users choice - not mandatory.
