Sony has made the previously optional firmware update, version 3.15, a mandatory update.
If you haven't installed it already you'll get the prompt next time you turn on your PS3. As previously reported, the update allows for PSP Minis to be played on PS3 with upscalled visuals, and adds a new Data Transfer feature, which lets you move all your data on one PS3 directly to another easily (in case you grab a PS3 Slim, we presume).
Here's how to do it:
1.Turn both the current PS3 (A) and new PS3 (B) on and connect them with a LAN cable; PS3 (A) should be connected to the TV
2.On the XMB of PS3 (A), scroll to the Settings menu and select [System Settings] and then [Data Transfer Utility]
3.Follow the instructions on-screen and transfer data
4.After transferring the data, follow the instructions on-screen, and then connect PS3 (B) to the TV to view the XMB
5.If content that was downloaded from PlayStation Store was transferred as part of this operation, you must activate PS3 (B) before you can use the data. Log in to the PS3 system as the user who owns the content, and then select (PlayStation Network) > (Account Management) > (System Activation) to activate the system"
