Motorola RAZR V3

so im working on my second Cingular branded Razr and have had the same problem on both phones. When i get a call, and sometimes when i place them, the speaker sounds like they are talking through a fan and apparently i do too. the first phone what replaced under the recall in march but the second one has started doing it as well. is anyone else experiencing this problem?

and another thing. has anyone ever tried to bluetooth sync two razr's or any motorola models to the razr and been successful? i could do it with my s710a to razr but now i cant connect motorola to motorola. anyone know whats going on here?
