Also consider WireframeSketcher, a desktop wireframing tool: http://wireframesketcher.com
It comes with mobile stencils for iPad, iPhone, Android and Windows Phone. The tool comes with fast and native UI on Mac, Windows, and Linux. Use PDF and HTML export to view and test prototypes on your mobile device. You’ll need to self-host HTML files but I recommend using Dropbox so you can easily link them online.
I’ve been using the InVision app this week: Desktop-sized prototyping has been great, but the mobile viewports have been challenging.
