Apple’s iOS 4 offers a number of amazing new features and compelling reasons for users to upgrade. The performance is all around, MUCH BETTER, and the enhancements to apps are definitely above par. Like clockwork, Apple has once again offered up numerous improvements to the iPhone’s software in the most recent operating system upgrade release. Have you upgraded your iPhone’s operating system? you’re still not sure of everything the new version has to offer, take a look at the new …

changes (top 5) that took place in the recent upgrade to see what you’re missing out on, and what you can start taking advantage of!


Sorry to those of you with 3G, you won’t be able to take advantage of this one. The new multitasking abilities work pretty dang well! It not what you get in the full OS X, but Apple has smartly implemented seven separate services that allow applications to continue to perform tasks while the user switches to another application. Why only seven? To preserve battery life. Multitasking includes: background audio, background voice-over-IP (for Skype), background location (GPS), push notifications, local notifications, task finishing, so uploading photos isn’t interrupted just because you switch to another app; and fast app switching.

Better application management

It’s amazing the difference folders makes! On my phone, I had 8 or 9 pages full of apps and I could never remember what was where, beyond my second page! Now I can group them into folders: Social, Music, Entertainment, News, Weather, Shopping, etc.

Better Enterprise support

Exchange 2010 now works with iOS 4, and the iPhone now can sync calendar, contacts and e-mail with more than one Exchange account. Sweet! Security has improved as well!

The little things

iOS 4 on the 3GS can now refocus video — while recording — with a simple tap on the screen. Tap-to-focus has been around for still photos since version 3, but the ability to refocus for video is a new and oh-so awesome! Speaking of camera improvements, digital zoom has been enabled for use when snapping photos!

Hundreds of new APIs for developers

There are also hundreds of improvements that will allow developers to make us better apps both iPhone and iPad. Just a few examples of features developers can add to their apps include: iPod remote control accessories; in-app SMS messaging; spell check; photo library access; Quick Look for document viewing; full map overlays; access to still and video camera data; access to date and address data detectors; and access to Calendar data.

Bottom line: iOS 4 = AWESOME

Between the new features and the fact that the upgrade is FREE, you’d be silly not to download the upgrade ASAP!
