personally I don't care as I don't use the PS3 browser anyway but I've seen heaps of requests for a new PS3 browser so as they finally did it and updated it I guess that is half there, now just someone needs to get it working in CFW.
If the first step is getting the keys then why haven't we already got them? It's been ages now since 3.56 came out so why haven't we got the keys yet?
here is a link to Kiosk/Shop firmware 4.10 this is intended for that guy who is making 4.00 custom firmware maybe he can extract dev_flash and create install package files on 4.10.. do not install this on a retail console it might just say corrupt firmware or could just brick your system!
Yup, that's the ONLY reason I haven't updated my ofw PS3 - been waiting for dropbox support! Now, instead of being able to play more file formats, I can just share/pirate videos to other users by sharing the account. Thanks, Sony!
