I always have the need to install things or alter themes as i like, or just change the images and put them back on the iPhone.
I have apps that are not able to get from Cydia anymore and have saved them from before.
Well with a few free tools available I have been able to reinstall them and also save to and from the iPhone.
One of them I use to be able to get to work, Seems it's a trick now to get it to work and since I have redone my laptop now it just crashes.
If you want to try to see if it works for you then try the iPhonebrowser
The new one I am using now is more friendly. It's called Diskaid I like it better.
