PS3ITA CFW v1.1 Changes include the following, to quote roughly translated:
Changed one patch.
Fixed error 80028f17 (All PSX games downloaded from the store now work!)
Stay tuned for more PS3 Hacks and PS3 CFW news, follow us on Twitter and be sure to drop by the PS3 Hacks and PS3 Custom Firmware Forums for the latest PlayStation 3 scene updates and homebrew releases!
From their site, roughly translated: We were waiting for new online game about developments on custom firmware (see kmeaw, geohot and others)
When one of the brightest minds of our team has produced what we call might, the fastest possible access for the PSN.
The firmware is based on Kmeaw's custom firmware, which were added to 2 small patches which allow access to the PSN!
Access is fast, no PC is needed to serve as a "bridge" and then programs like FckPsn or charles, skipping the check of the model (debug, retail, reftool, etc..) And setting of the PS3 fw at 3.56.. (Not in the XMB)

Of course the risk is still high and BAN of Being a CFW, PS3ITA assumes no responsibility for any brick during installation.
