    I want to know why the CDMA version has a large hump at the earpiece while the GSM versions are pretty much flat. Is the speaker different? I have taken mine apart, not this particular one, but the last one (this is number 6).

    I have heard the hump is for radio wave protection as in the Sprint model the waves are greater intensity. 650's all have hump.
