Hi! #2 design looks modern however would be see however one see this type "woosh symbol" quite a lot someting that reflects datacomms eg wireless would be interesting. Great work, I amstarting to get a feel.
#3 the symbol not reflective of what mandate is, however the line under Telsure works for me noe willl see later, however logo must be modern, eye catching ....because what we want is that people must immediately say when they see our logo, symbol etc that they immediately say .that's TelSure.
WRT #5 I have just ckecked one of my competitors and their logo looks just about the same as mine. Can you see what else you can do. I like modern look, see Telstraclear.co.nz.
