14 Free Mobile Application Development Icon Sets

Mobile web site Design and Developmant

The gap between the desktop/laptop and the mobile device is becoming smaller and smaller, it has never been a better time for mobile app development – The market is huge, very lucrative and highly profitable. Our ever growing appetite for more powerful and better mobile devices has pushed the demand even higher for ever more powerful and better applications to accompany them.
The expectation on the apps UI design is just as demanding. The design has to not only be consistent with whichever mobile OS you are developing for, it also has to be distinctive enough to be unique. And yes, we do love a well designed app.
In this post we are sharing 14 free mobile application development icon sets. For the most part the icons below can be mainly used for the iPhone or Android, there are even some Symbian icon sets, but for the life of me I could not find a single free icon set for BlackBerry development. Anyone know of any?
