Pojiku does not only released a wonderful PC app now he has made a downloadable online website of FreeStore where you can easily download your favorite PS3 Jailbreak homebrews. I am not sure if you can browse it with your PS3 and download it straight to your console, but you can always give it a go.
Anyway, the new version of FreeStore will be released soon by Pojiku, until he finished it, here is what you can expect from the new version, this is coming from the Pojiku himself:
Online version of FreeStore released. Simply navigate to freestore-ps3.com to download and install the latest homebrew without restarting your PS3. (USB Drive Needed)
I have also made an update to the FreeStore PC app but it’s currently needing a big re-write to deal with the USB method. As soon as everything is stable, I’ll post the update here.
FreeStore 1.0.5 will install apps without restart, allow multiple downloads and be compatible with OS X
