It is no state secret that the latest Apple firmware for its iOS devices has been released. In fact, it went on air since Monday, 22nd November 2010. The update came with several new innovative features and a compelling ground for anyone using an iOS device to upgrade.


The devices supported in this update are the iPhone 3G, iPhone 3GS, Iphone 4, iPod Touch 2G, iPod Touch 3G, iPod Touch 4G and the iPad.

There are said to be more than a 100 new features and tweaks to the iOS 4.2.1. I would only list a few of the major new features relevant to our environment (Nigeria) and peculiar to this particular update are;

  1. Airprint
    AirPrint makes it simple to print email, photos, web pages and documents right from your iPhone, iPad or iPod touch. All you need to use this feature are a few taps and availability of Wi-Fi and a Wi-Fi compatible Printer. There isn’t any new needed software to download, no drivers to install and no cables to connect before using Airprint.
  2. Airplay
    AirPlay allows you stream digital media wirelessly from your iPhone, iPad and iPod touch to your Apple TV or AirPlay-enabled speakers. So you can watch films and photos on your widescreen TV and play music through the best speakers in the house through Wi-Fi or yourinternet broadband.
  3. Enhanced enterprise support
    Businesses can take advantage of stronger security features, new device management capabilities and improved enterprise integration.
  4. Multitasking on iPad
    This is a new feature for the iPad. Any need to say that other iDevices have been enjoying this for long? iOS 4.2 brings multitasking from iPhone and iPod touch to iPad. The implementation of the multi-tasking is okay, every running apps work smoothly and efficiently — without slowing down the performance of the foreground app or draining the battery unnecessarily.
  5. Folders on iPad
    Also new to the iPad. The ipad now has more rooms for more apps. You can now move apps into folders with drag-and-drop simplicity to declutter your Home screens and keep your apps organized for quick access. Should I say that I find this functionality invaluable for my iDevice. At last count the total number of apps on my iPod touch 4G/iphone 3G was about 312! About 5.3 Gigabyte in size! And there is no slowing of the UI or memory error on account of these number and size of apps! SO this option was really cool for me to keep my apps organized
  6. Game Center
    Also new for the iPad. You can get more social with your gaming, Find friends or use auto-match to play multiplayer games against new opponents. Track achievements and compare high scores.
  7. Even better Mail
    You can now See messages from all your accounts in a unified inbox (New to ipad) or separately. You can now also organize messages by threads and open attachments in third-party apps.
  8. Find My iPhone, iPad or iPod Touch
    Find My iPhone, iPad or iPod touch is the MobileMe feature that actually helps you locate your missing iDevice in real time and protect its data. The icing of the cake is that it is now free on any iPhone 4, iPad or fourth-generation iPod touch running iOS 4.2.1. Once you set it up, you can find your lost device on a map, display a message on its screen, remotely set a passcode lock and initiate a remote wipe to delete your data. And if you eventually find your iPhone, iPad or iPod touch, you can restore everything from your last backup. Set up is easy; Just read the step by step guide at:

Other features include: Find text on web pages in Safari, Notes with fonts, Reply to calendar invitations, Keyboard and dictionary enhancements, Accessibility enhancements, and a host of others.

The ios 4.2.1 is a welcome update to anyone using any iOS devices. I just got an iPod touch 4th Generation, and after upgrading to to 4.2.1 (8C148), the improvement in the User interface along with the everyday usability tweaks in the new firmware was profound.

An area of praise is the Find My iPhone, iPad or iPod Touch feature. It used to be a paid service but it is now free. All you need to do is to sign up for a free mobileme service in your iDevice, if you don’t have an account before and then activate the Find My iPhone, iPad or iPod touch feature under settings in your device. And presto, you can now go! If peradventure you misplaced your iDevice, all you need to then do is to Sign in to from a computer to see your iPod touch on a map, or display a message on it or set a passcode lock. Or you can even remotely wipe it!

You can also do these on another iDevice after installing a Find my iphone app! This is a Neat feature, if you ask me.

So what are you waiting for? Go update your ipad or ipod touch! But there is a word of caution to be sounded at this moment. If you are using a Jailbroken iPhone, then you MUSTN’T upgrade immediately, or otherwise you would Re-Lock your phone. You need to wait until a Jailbreak for the new version is available before upgrading to iOS 4.2.1.


  1. Airplay is an interesting feature. But the free Find my iPhone feature beats me.

    I gave it a try and I could remotely send text messages and make my iPod touch to ring remotely. This feature is nifty if you misplaced your iPhone in your house and it was turned off before getting missing.

    I was also able to lock the iPod touch remotely and wipe out all the data with the free mobileme service. I was able to restore the data with RESTORE following an earlier Back up.

  2. This update is a must for all ipad users.
    Its turns your device into a totally different one.

  3. Hey there! Quick question that’s totally off topic. Do you know how to make your
    site mobile friendly? My web site looks weird when viewing from my iphone.
    I’m trying to find a theme or plugin that might be able to resolve
    this problem. If you have any recommendations, please share.

    With thanks!
