I can't believe on Day 1 such results are coming in...AGAIN, first and foremost Design what you would if PhoneBelle was your company. My guidelines are just a suggestion, I envision the "feel" or vibe but actual logo I cannot hold a candle to what I have seen....
1) I like the idea of symbols above the word or in the 'O' of Phone
2) I like the idea of a silhouette leaning on the word or the symbol itself looking at their phone. Silhouette can be singular (asexual) or 2 male and female either leaning on the symbol or back to back.
3) after looking at pc from a distance, black or white background stands out best...splash of colour can be orange or champagne.
4) Threw in some fonts I thought were cool or how the "e" blended with the "b" in the word "belle"

feedback please
