Adobe has updated Acrobat XI and Reader XI to version 11.0.02 solely to improve the security of the two apps. The updates address critical vulnerabilities in versions 11.0.01 and earlier, vulnerabilities that could enable an attacker to take control of your system (detailed over at The Next Web). The update for Acrobat XI is just 11.9 MB; meanwhile you can choose between the delta updater (25 MB) or the full installer (76.6 MB) for Reader XI. Additionally, Adobe recommends that users of older editions of Acrobat and Reader update their software as well, with Acrobat getting version 10.1.6 (13.5 MB) and version 9.5.4 (10.8 MB). If you can’t update to Reader XI 11.0.02, you can similarly choose version 10.1.6 (17 MB) and version 9.5.4 (5.4 MB for Intel, 5.6 MB for PowerPC). ($449 new for Acrobat XI Pro, free updates)
How to Make an iPhone Screenshot
Want to take a screenshot of something on your iPhone or iPod touch? Press the Home button and Power button briefly at the same time, and an image of your screen will be saved to the Photos app (and will sync with iPhoto when you next connect). Don't hold the buttons too long or your device will either power down or reboot.
