Appreciate the entries! My concern with #116 and #115 is that it's too similar to ATT's logo...I think. Some of the other designs that incorporate the circle but have the design not confined to the borders of that circle seems to stand out. Perhaps play around with that a little more.
Had feedback from a team member to focus on integration similar to entry #106 (although we are not a huge fan of that design). See what you can think of.
