Apple has just released the fourth beta of iOS 7 firmware for iPhone, iPad and iPod touch to registered developers only. The build number of iOS 7 beta 4 is 11A4435d and it weighs in at around 200-250 MB. So, if you are not a developer, you can simply do an OTA (over the air) update for it.  We have tested it on our devices and it worked out successfully. This update comes three weeks after the release of iOS 7 beta 3, so this means that the next 2 betas, to be seeded before the GM version, will be dropping in the following weeks surely.  
                                                   

 It is currently available for the following devices : 

  • iPhone 5
  • iPhone 4S
  • iPhone 4
  • iPad 4
  • iPad 3
  • iPad 2 
  • iPad mini 
  • iPod touch 5G 

The software update is available over-the-air through Settings > General > Software Update, As always, we will be posting the unofficial download links of this firmware for all our readers who are not developers. 

 Here's a change -- there is a new white colored right arrow icon placed right next to the “slide to unlock” text. Also, the tabs for Control Center and Notification Center now seem much more straight and devoid of skeumorphism.
