i own a treo wireless bluetooth headset. everything was working great, till i paired it with a motorola krzr mobile phone. now when i try to re-pair it with my treo 680. the 680 tells me i'm connected, but i cant head anybody who calls and when i tried to answer a call by hitting the multifunction button, it doesnt answer. has anyone experiece this kind of issue?

i read somewhere that i should de-pair it from motorola krzr.
