Cyder 2 application will let you manage everything in Cydia straight from your PC. Cyder lets you sync, download/update packages and install them to the iPhone and it’s wicked . especially for people that can’t get 3G speeds or Wi-Fi.
Changelog (used Google translate):
* Import Sources rest of your Cydia on your device in Cyder.
* Cydia Auto Setup: iPhone reboot to finish installing the debs.
* Cydia Cache: Install with Mobile Temrinal / private / var / cache.
* AppCake Folder: Launch application after AppCake transfer debs.
* Download and store on your computer the application of Cydia with its dependencies.
* Install on your iPhone or iPod Touch into USB.
* Compatible with the application AppCake (Cydia application that allows the installation file debs)
Basicamente es un programa para pc que "emula" el cydia. Puede exportar e importar tanto las sources como los paquetes que hayas instalado. Genial para backups y cambios de firmware.
Aun lo estoy probando, pero tiene muy buena pinta.
Os lo subo por si quereis echarle un ojo. Saludos
