Hi
For some feedback,
Rimfire, I REALLY like your black logo how you were able to use all three colors. I too can picture a simular logo I just can't think of where I even did a few google image searches for what I thought and I was wrong.

PXS I like your second two (the ones on the right) I just feel the signal coming from the I is a little to powerful,

Jonathanober I like the look for yours but I am going towards more of the "wireless" type feel, how the other entries have been with the signals and antennas type look.

Thanks everyone for there hard work and entries!
