Note: if you have a 2.0 iPhone and have Cydia installed, try WinterBoard which is now the new version of SummerBoard for newer iPhone/iPod touch users.

Have tons of native 3rd party apps on your iPhone? If so you are probably running out of space on your iPhone springboard (your iPhone homescreen). The Summerboard native iPhone app that enables scrolling on the springboard for your iPhone, so now you have unlimited space for native apps. Download and install SummerBoard via either Installer.app or iBrickr depending on your OS.

Below is a video demo of SummerBoard:

Summerboard now supports themes and they are now available for via installer.app. Some of them include: Oren, Phiberglass, JrWallace, and two variations of Tiger. You can also develop your own themes. Here is another example theme called colorGrid iPhone. SummerBoard themes are designed to be easy to make and reside on your iPhone. When making a SummerBoard theme, you name the PNG by what the app name looks like on the home screen, so for example: even though Photos and Camera are theoretically in the same app, you name the files Photos.png and Camera.png. Here is what the folder paths look like in /var/root/Library/SummerBoard/Themes/. You have a folder per theme with the following structure:

ThemeName/StatusBar.png - Status bar image (optional, 320×20 PNG, no alpha)
ThemeName/Wallpaper.png - The wallpaper (320×480 PNG, no alpha)
ThemeName/Dock.png - The dock image for the large dock (320×91 PNG, alpha)
ThemeName/MiniDock.png - The dock image for the mini dock (320×37 PNG, alpha)
And your icons (optional, 59×60 PNG, alpha) go in: ThemeName/Icons/

Use iPhone mods and hacks at your own risk! Installing 3rd Party iPhone apps requires you to jailbreak the iPhone before installing the native software and apps. You can use Installer.app for Mac OSX and iBrickr for Windows PC to do this. Browse the full list of all iPhone and iPod touch native 3rd party apps filed under the software category.

Here is how to manually Upload New SummerBoard Themes that you find online:

2. Find your iPhone’s IP address: Go to the Home Screen > Settings > Wi-Fi > [Your Wi-Fi]. Look for the DHCP IP address. (Something like 192.168.1.10 etc.) This depends on the Wi-Fi network you are connected to at the time.
3. Disable Auto locking on your iPhone to make sure the device doesn’t fall sleep while you try to FTP to it. Settings > General > Auto-Lock > Never
4. Open up any FTP program (FileZilla for Windows, or CyberDuck for Mac) and create a new connection to your iPhone.
   Host: [THE IP ADDRESS]
