Any links or guides to some of the available tools and uses of SSH and WinScp with jailbroken 3g 2.2.1 iphone would be appreciated. How to add ringtones for mail and text, change desktop backgrounds, etc. Any direction or helpful links is apreciated. Anything people found pretty cool that you can do to the phone using ssh or even cydia would be apreciated as well. i am faily new to a jailbroken iphone and want to make the most out of it.
