I've learned how to SSH and stuff but how do i put a theme from the internet into my iphone 3GS from my computer? I'm quiiiite confused. Any help is appreciated.
I used Iphonebrowser, just download it from here http://code.google.com/p/iphonebrowser/ When you start the program up it has a tab at the top "Go to location" then select Winterboard Theme i belive, and it automatically takes you to that directory where you can copy the files. BTW make sure you have OpenSSH installed through Cydia. Hope this helps!
Second for DiskAid, I was able to dig out a malfunctioning app thanks to that program. I got it initially as an easier method for managing ROMs, but its just so much more useful.
I also bought TuneAid, but it has yet to support 3.0 (may never).
