The Sony Ericsson has good call volume and the loudspeaker volume is the loudest I've ever heard (because it has two speakers). It has MP3 capability and a huge memory to hold it. Cingular offers it.
I just got the Sony Ericsson z520a after signing up for a 2 year contract with Cingular. The phone for the most part is okay minus the auto-fading screen and the low call volume. I need a phone that has a loud call volume AND speakerphone where I can hear in the car with moderate road noise. If anyone could help on this matter I would greatly appreciate it. I would like it to be able to hold mp3 ringtones as well but could care less about the camera. And preferably a phone that cingular offers since I have the 30 day exchange and already signed the agreement. Any help you can provide is most appreciated.
