I think you are going somewhere with these, but we do not want to use the actual shape of a phone in our logo. I like to text in #3 and the squares in #4.
For #8: could you create this with the squares not on a tilt like that i like it just as a plain square, same design. then jac apps a thin classy weighted font the font like in entry 7 for the word "jac" something cool happening there
#48 try exploring other directions, think outside the "box" keep with the technology but stay away from a web 2.0 look. Play with different fonts and weights. Treat the typography as part of the logo, alter the type and make it work with the mark.
#115 interesting as well thinking the J should be incorporated into the last column of squares in that grid the j needs to be smaller in proportion to logo mark size
Can you change the colors of the little squares back to what they were like in #48 except for the one really dark square. Also, can you space the jac and apps the same distance as rest of the type. Please keep the grey and black in the font the same as #477. thanks!
