Creating your logo yourself will protect against copyright claims, but it won't protect against trademark violations.

Apple sued Prepear because Prepear's logo looked too much like the Apple logo [1]. Prepear spent lots of money to defend themselves and finally made a small change to the logo to make Apple happy.

I think the lesson is to be prepared to change icons and logos swiftly when another legal entity sues for copyright or trademark violation.
