It’s always the way. You spend months drawing and building your own mockups – then just days after we finally launched our Skype for Symbian client to the public, Nokia get round to releasing a set of wireframe stencils for designing S60 3rd Edition and 5th Edition applications:
Forum Nokia’s Wireframing Stencils are a collection of customisable user interface views and components. The stencils can be used to create quick mockups or formal wireframes. […] This package includes stencils for S60 5th Edition touch devices and S60 3rd Edition non-touch devices, both in Adobe Illustrator CS4 format and Adobe Fireworks CS4 format.
From a cursory glance, the set seems fairly exhaustive and contains more or less everything you’d need for both portrait and landscape layouts, covering regular list views, menus, alerts, grid views, virtual keyboards and even 5th Edition home screen widgets.
