Does anyone have a list, or can point me to a web URL showing which mobiles sold in Australia can be used with my IS250 built-in phone system? My Blackberry 7130e works brilliantly but my wife's Samsung SGH-Z510, which pairs OK produces very distorted/crackly sound - to the point where the quality of the connection is useless. I have found a US link with a list but this does not apply here as many phones are not available plus there may be technology differences.... :(
