According to several sources, Sony has released it's newest firmware update (v3.15) on the PS3. This update is completely optional. In order to access the update you need to select the 'System Update' tab, you will then be prompted with a set of instructions, and a list of agreements to read. A few new notable additions in the update include, the ability to play PSP Minis, as well as being able to Data Transfer. Keep in mind, not all PSP Mini titles are playable on the PS3.

When it comes to PS3 development, cross-title communication is one of the most – if not the most – frequently requested functionalities.  The Xbox has it, we all want it, but there has been no edivdence to suggest that Sony will implement it any time soon. Until now.

A VG247 source has recently claimed that Sony plans to incorporate cross-title voice chat in Firmware update 3.10, which is scheduled to arrive before the end of October.

However, it is not known who VG247’s unidentified source is, or how legitimate the leaked information is. Forgive our scepticism, but until official word comes from Sony directly we shall refrain from holding our breath.

The Official US Blog has detailed some features of Firmware 3.0. It's all listed after the break, along with a video showcasing it. And yes, they're moving the battery indicator from above the clock. Victory!

There's no date for it yet, as we've still got some firmware updates to go before then, surely, but it's a nice update and something to look forward to.

You might've seen reports of PS3 firmware 3.0 details  floating around the internet. These reports said that the firmware will release before Christmas and was a 'huge overhaul' to the XMB, comparing it to 306's NXE in that respect.

The updates promised for the firmware were a reputation system, a griefing reporting system, simultaneous sound output through HDMI and digital optical cable and, the most interesting of the promised additions, background downloading of game patches. We want that one.

The origin of the rumour was VG247, who ended the article with an arrogant 'Just remember where you heard it first'. Joystiq contacted SCEA, who proceeded to say 'Those rumors are completely untrue, nothing has been announced or confirmed for upcoming PlayStation firmware, and this is just wild speculation.' So it's untrue.

Of course, that's exactly what you might expect Sony to say, but there you go. Let's just cross our fingers for background downloading of patches, eh?
