Thank you for these 3 proposals. No doubt, the "entry #3" is the best one.
The fact is that our website will be in a white background. So, the "entry #7" could not be used. No matter, you probably give us a "transparency background". So, the background must be, in these proposals, a white one.
Othermore, the "font style" used for the entry#3 is, in our opinion, more "redeable" (we can separate better the 3 words : Top... For... Phone).
Could you try some different styles ? And, just in order to see, could you do a logo with only one "mascot" at left, and the brand name+slogan in its right side ?
Other more, maybe could you test a different smile (just in order to see what it looks like). (a lot of demands, but one more time, the job is damned good ! ;))
Just one comment : on your #65 and 66, your third mascot (with the opened mouth) seems to eat a CD. I know it's strange like remark, but when I see it first time, I thought there was a CD in its mouth. Could you try another color of mouth or another think ?
