SMITH MICRO SOFTWARE'S CONSUMER GROUP RELEASES NEW SPRING CLEANING 10 FOR MAC

Spring Cleaning 10 Cleans, Protects and Organizes Files for Maximum Performance

ALISO VIEJO, Calif. - September 8, 2008 - Smith Micro Software, Inc.
(NASDAQ: SMSI) Consumer Group today announced the release of Spring
Cleaning 10 for Macintosh, which boosts performance with over 50
easy-to-use tools that help users clean up file clutter and better manage
content on their Macs, reclaim more disk space and perform comprehensive
system maintenance.

Spring Cleaning 10 introduces additional benefits for a more comprehensive
feature set to meet challenges Mac users face today. For example, the
dashboard provides a single interface to the Mac's content, with the
ability to better organize, search and move files, batch, rename photo
files, archive and burn files for off-site storage saving disk space,
automating common tasks with scripting and much more.

"Spring Cleaning 10 makes file management on the Mac easier and faster than
ever before," said Fletcher Wu, Product Manager, Smith Micro Software, Inc.
"This new version helps Mac users at virtually any level to better organize
their Macs and save time while maximizing available space on the hard
drive."

New Features and Benefits:

* File Sorter - File Sorter uses customized criteria to organize all types
of files, including documents, images and music, into folders according to
file type, size, date created, date modified and more. Users can now easily
organize folders into sub-folder groups similar to a filing cabinet so
files are easier to access and manage.

* Photo A.K.A. - New to Photo A.K.A. is Picasa and Flickr support, which
enables users to rename, resize and upload photos directly to online photo
albums on Flickr and Picasa websites. Photo A.K.A. also includes support
for importing images from cameras and seamlessly exporting them to iPhoto
with meaningful file names. Additional features include burning files to
disc, saving files to archives or disk images, emailing files, resizing
images and uploading them to web services.

* Movie Finder - With the ability to identify 17 common video formats,
Movie Finder uses a single interface to find all videos on the Mac,
including QuickTime, Windows Media, MPEG, Flash, AVI, iMovie projects,
TiVo, DivX, Google Video, DVD files and many more.

* Podcast Finder - This tool finds files on the Mac recognized as podcasts
by iTunes and keeps them in a single, easy to search library. Instead of
manually searching for podcasts scattered around the Mac, users can save
valuable time by using Podcast Finder to quickly locate podcasts that users
want to delete, archive, or burn to CD/DVD.

* Application Scripting - Spring Cleaning now supports AppleScript and
other scripting languages such as Python and Ruby by utilizing the
Scripting Bridge support in Mac OS 10.5. This will allow users to create
their own scripted workflows to automate common Spring Cleaning tasks.

* Poser Integration - Spring Cleaning helps Poser users collect and import
scene content to better manage their extensive Poser Libraries. Leveraging
Spring Cleaning 10's new scripting support, PoserPython's scripting support
facilitates collecting scene inventory and packaging it in disk images or
StuffIt archives for delivery.

Spring Cleaning 10 offers smart, powerful search tools to locate music,
images, archives, widgets and more. It also includes popular features from
past versions such as task scheduling to automate common and repetitive
tasks, and the ability to fix permissions, easily identify and delete
duplicate files, and search and locate lost email attachments
