I currently have boost mobile sim card in a ugly Motorola. I wanna buy a better Motorola from eBay but all the phones say "carrier "Nextel/sprint" does anyone know if Nextel and boost mobile are interchangeable w/ the sim's or if at least I can put a boost mobile card in a nextel phone and be able to use it?

Sprint can't take SIM cards, and the Nextel aspect doesn't actually use GSM service (they use something similar called iDEN) which is what your sim card is set up for.

Unfortunately the short answer is 'NO'

Though the nextel phone has the SIM card slot, it's totally incompatable technologies. My apologies.

Hope this helps!
