You might want to upgrade your phone if you're a single man.  

A study by dating site Match says women are 90-percent more likely than men to judge their date negatively--for having an older model of phone.  

Three-quarters of singles said they would be turned off if their date answered the phone without any explanation.  

Just having a phone around could be a hazard.  60-percent say they don't want their date to place the phone on the table face up.  And, 40-percent say it's rude when someone takes their phone to the bathroom.
