First of all, the Facebook application now comes preinstalled. Previously, this was available in BlackBerry App World, but now it will come with the OS. The Facebook app has also been updated and now includes video uploading, message deletion, as well as Facebook Search enhancements. There's also improved access to pages, and News Feed improvements.
Next up is support for in-app payments, which the 1.0.5 update finally brings. In-app payments are all the rage these days, allowing your kids to buy silly virtual animals for loads of actual money.
Alongside these more important additions, many enhancements have made their way into this update. For example, you can now charge your PlayBook even when fully powered down. If you touch the battery indicator, a new pop-up will appear and allow you to quickly turn off, restart, or put your tablet to sleep, in addition to setting the brightness (this new pop-up can be seen in the picture above). A very useful little new feature there.
You'll also be alerted if you stick an incorrect charger into your tablet, additional languages are now supported, video chat now works behind corporate firewalls, automatic Wi-Fi hotspot detection is now active during the set up process, and finally, Headset Audio Boost gives you more volume for when you need it the most – in an airplane when you're surrounded by screaming kids who've just maxed out daddy's credit card by purchasing virtual fish and/or farm animals.
The update will reach your tablet over the air. If you're impatient, just go to Software Updates in the Settings Menu and force a manual download. If you're going to purchase your PlayBook after today, it should come with OS version 1.0.5 preinstalled, so you don't need to worry about updating.
