Idea of BlackBerry World Icon
It's a logo of Blackberry App World reduced to the blackberry icon. The icon is enclosed by a circle the borders the logo. It pretty much looks like the same Blackberry icon on the back of all of the blackberry cell phones.
This is a BlackBerry World icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,900 icons, all in the same style and quality.
