In this version, you’ll notice the addition of the PlayStation Network icon on the XMB. You can now sign up for PlayStation Network, manage your account and access PlayStation Store directly from your PSP - meaning you can download games directly to your PSP while connected via Wi-Fi. Getting games, demos and trailers while on-the-go has never been easier!

The current PlayStation Store on the PC will be down in the interim as we take some time to revamp. Don’t worry, it will re-launch soon after we’ve made some tweaks. Please keep in mind, if you already have a PlayStation Network account, simply sign in on your PSP using your existing information. The same account and wallet can be used on PS3 and PSP. You will be able to check out the PlayStation Store on the PSP soon, as we’ll have a video demo featuring Grace Chen posted soon on the Blog.

Update v5.00 adds a sleep timer option that can be used while you are playing music on your PSP. In addition, we’ve added a full screen keyboard option for text entry and have redesigned the background of the XMB.
