#6 - green + dark grey (or is it black?) is fine; the text mobileTECH is quite ok - i like the capital letters for TECH; but the symbol is for me something like "too much"; i understand mobile and the currency symbol (even for us would be better €...), but i am looking for something, whet is between "abstract" and "too much concrete".
#10, #9 - texts are not ok, do not like the bolds; the symbol - similar like by #6
