Yes there is a preety good solution !
U guys mite not kno abt. it , but there is a pretty good solution to this . Download imediashare from the app. store for free or u can buy for 2.99 if u want full features. For the jailbroken iphones, just goto installous or appcake, and download imediashare full version for free. That's it. As you start the imediashare application in your iphone, ur ps3 will show it. If not go to the"search of mediaserver" option from the video icon of ps3 and after a few second your mediaserver will be detected below the video icon. Now, u r good to go.......u can either stream live videos from iphone's or can copy to ps3's hardware.
Thanks
