IOS 4

Apple introduced iOS 4 as an upgrade for iOS3G and iOS 3GSdownload is free for both iPhone and iPod Touch users, but it is incompatible with first-generation models of either device. 

The iPhone 3G will support most iOS 4 features except multitasking and home screen backgrounds. iOS4 marks a significant and welcome jump in the iPhone's evolution.

Naturally, new hardware tends to get the biggest spotlight, but iOS 4 brings a handful of crucial features like multitasking and a unified e-mail in-box--that Apple's products have lacked for far too long. iOS 4 is set to offer up to 100 new features--even if they're not particularly glamorous.
Multitasking in IOS4

Apple's multitasking works a little differently than on other smartphones. Instead of having all device resources available to every running app, iOS 4 lets only seven app services run in the background. These include audio, VoIP services like Skype, GPS/location for apps like TomTom, push notifications, local notifications (those that don't to have to go through a server), task completion (users get an alert when a process is finished), and fast app switching (apps essentially hibernate not to use the CPU). According to Apple, this arrangement will have less of a drain on resources like battery life and memory than if it gave developers free rein.

Though some have complained that the built-in limitations mean that iOS 4 doesn't have "real" multitasking, we think "incomplete" is a better description. Granted, you can't run everything in the background, but iOS 4 does allow you to run certain features from multiple apps simultaneously. If that isn't multitasking, then i don't know what is. What's more, it wouldn't be the first time Apple limited features or took longer with development in order to produce a desired customer experience. You may not agree with such a philosophy, but Apple has always been honest about pursuing it. Like with so many other things in technology, it comes down to what works best for you.

To enable multi-tasking and wallpapers on your iPod touch 2G, jailbreak it using redsn0w and enable it. Very easy. Works flawlessly on the iPod touch 2G.

E-mail in IOS4:

Though the iPhone always has been a functional e-mail machine, we never enjoyed switching back and forth among multiple accounts to read new messages. Fortunately, iOS 4 has a new unified in-box that is accessible under the "Mail" option on your home screen. With this feature you can move or delete multiple messages at once from a list of search result which is useful for those who rely heavily on mobile to check their mails. Listed above your individual in-boxes is a new option for "All inboxes," which contains messages from multiple accounts. You can't access individual folders from the universal in-box, but you can delete and move messages.

Upgrade from iOS3 to iOS4:

If you own an iPhone 3GS then you might think of upgrading to iOS4 with lots of new features. The introduction of iOS2 and iOS3 both saw older phones take a performance hit and suffer major stability issues that were only resolved with further updates. It generally takes a while for Apple to acknowledge there's a problem, so don't rush in. I would suggest to wait for about a month or two and then go for an update.
