Help Icon Mystery

[tomandcindybates]

Hello,

I have an icon I cannot identify. It is located on the in the Notifications area, on the right, just left of the Wi-Fi Strength Icon. I have attempted to draw this icon and, as a warning, I am not an illustrator of any sort so be forewarned.

Please take a look and advise its meaning.

Thanks in advance.

Come on my friends, I am sure someone else has seen this icon on their Motorola Defy (XT555c)

I've never seen it - However, I did some research and found this:

I also checked it on my old Defy & confirmed it looks very similar to your drawing - so apparently it means you have TTY turned on in call settings
