The 4th-generation iPod touch is a portable media player and personal digital assistant that was announced by Apple at a special event on September 1, 2010 and released on September 12. This iPod touch was set at the price range of $199 to $399.[1] It originally came in just a black model, but a white version was later introduced in a "Let’s Talk iPhone." event on October 4, 2011, at the same time as the iPhone 4S.[2]

New features

The new iPod touch included many new features from the iPhone 4, including a Retina display, a FaceTime camera, and a 720p HD iSight camera. The 4th-generation iPod touch is 26% thinner than the 3rd-generation model. The iPod touch 4 first came in black with iOS 4.1, which included the following new features:

  • FaceTime: FaceTime video-calling was added to the iPod touch 4 with the front camera; it enables iPod touch users to call any Mac with video conference ability, iPhone 4 or later, iPad 2 or later or another iPod touch 4 or later and have a video chat (similar to Skype). To use FaceTime on an iPod touch, you need to use an email address.
  • iMessage: This app was introduced in the iPod touch 4 to enable users to freely text another Apple device (iPhone, iPad, Mac) running iOS 5 or OS X 10.8 (Mountain Lion) or later by using an email address. This feature became very popular among iPod touch users who did not own mobile phones, as it allowed them to text their friends.
  • Reminders: This app was introduced to the iPod touch 4 as an alternative to Calendar or Clock alerts, and a way to create a virtual schedule day-by-day. Reminders allows users to schedule events by date, time, and month, similar to the Calendar application, but actually alerts the user when it is time to complete the task they have scheduled.
  • Game Center: The Game Center was added to the iPod touch 4 as a gaming leaderboard where users can create an account, add friends and access their scores while playing games on third-party applications. Users also gain a ranking on worldwide leaderboards where they can connect with other players of the game.
  • Newsstand: This app was added as a way for users to read magazines and newspapers on their iPod touch, which they can download from the App Store. Users can also manage their magazine or newspaper subscriptions from the app.
  • Voice Memos: This app allowed users to record important moments in their lives by utilizing the iPod touch's built-in microphone and recording audio files. These 'memos' can later be transferred onto a user's computer.
  • Camera: This app works with the iPod touch 4's dual cameras to take pictures, record videos, and edit them all in one app. Similarly, there are synchronized sharing options within the app, so users can send their pictures to friends or post them on Facebook and Twitter with a tap of the screen. The iPod touch 4G is the first iPod touch model to have not only one camera, but two, the front camera is 0.3mp and the back is 0.7mp but supports HD video recording at 720p. There are apps on the App Store that make the camera better.
  • Retina display: The display on the iPod touch 4 is designed by Apple and manufactured by LG. It features a multi-touchscreen with pixel density of 326 pixels per inch (pip) and res of 960x640. The screen is marketed as a "Retina Display", based that 300 ppi at 12 inches from the eye is the maximum amount of detail the human retina can process.
  • Notification Center: This is a central place where iPod touch users can view all of their notifications from third-party and built-in applications and mark them as read. It is an easy place to catch up on what you've missed, especially if you haven't used your iPod touch for a few hours.

Updates

On October 4, 2011, Apple announced a new white iPod touch, which was still from the 4th generation iPod touch family as it had the same specs as the original black one. Its new features were enabled by the iOS 5 update that was released on October 12, 2011. It could support up to iOS 6.1.6.

Issues

  • Some 4th-generation iPod touch users experienced Wi-Fi signal dropping when texting and browsing the web. Other users experienced sound issues when recording video with Wi-Fi on.
  • The older, original 4th-generation iPod touch (with iOS 4.x before iMessage was introduced) doesn't work with some docking stations.[citation needed]
  • 4th-generation iPod touch models manufactured after a certain date were shipped with iOS 6, and could not be as easily downgraded like previous models.
  • Some users were upset that the iPhone 4 was supported by iOS 7, but not the 4th-generation iPod touch, even though both featured the same Apple A4 processor. This was attributed to the fact that the iPhone model had twice as much RAM (512 MB) than the corresponding iPod touch (256 MB). Some hackers had managed to install iOS 7 on a 4th-generation iPod touch, but found functional problems with audio output, Bluetooth, cameras, Multi-touch, sensors, and general stability, making it virtually unusable.[3]
