Imagio Status indicator unknown of its meaning

[tidurr]

I have a status indicator that suddenly has been on the top of my phone's screen for two days. It is 3 over from the right side (after the memory menu, and after the battery indicator). There is an icon that looks like a rectangle (long way vertical). The bottom part of the rectangle has a little more white than the rest. On the bottom right side of this indicator/icon there are 2 squiggly lines like this ( \/\ ) but imagine that design 90 degrees clockwise. There are 2 of those against each other.

Does anyone know what the heck this means??
