Apple seeded developers of iOS Developer Program with iOS 6 beta 4 earlier today, which according to the release notes includes some bug fixes and improvements.

Here’s the list of new features and changes in iOS 6 beta 4 that have been discovered so far.

MacRumors reports that Apple has removed the native YouTube app, which came preinstalled with the iPhone since it’s launch in 2007.

This doesn’t come as a surprise to us as the YouTube app was hardly updated since 2007 and we preferred to use the YouTube web app in mobile Safari, which is much better.

Apple has issued the following statement to The Verge about the removal of the YouTube app:

Our license to include the YouTube app in iOS has ended, customers can use YouTube in the Safari browser and Google is working on a new YouTube app to be on the App Store.

That worked out quite well from users point of view.

Update 1:

Privacy Settings now includes a section for Bluetooth sharing, which will show all the apps that have requested the ability to share data via Bluetooth (via 9to5Mac).

The Passbook app has been updated. It now includes a button that take you to the App Store. It looks like there will be a separate section in the App Store that support the Passbook app (via 9to5Mac). You now have a Shared Calendar Alerts under Mail, Contacts, Calendar in the Settings app. 9to5Mac reports that Maps experience has been improved: We’re also hearing from many users of iOS 6 beta 4 that the Apple Maps experience has been improved. People are seeing improved mapping data (especially in the satellite view), improved performance. Others are reporting improved font rendering as well. Another new tidbit in the updated Maps app is a the noting of one-way streets. Notice the blue arrows.

Update 2:

If you’re getting “unable to check for update” error when you tap on Software Update in the Settings app for the OTA update then there seems to be a workaround. Turn off Wi-Fi and then check for the update. The OTA update should show up this time, however to download it, now enable Wi-Fi and you should be able to install the OTA update. Thanks Alan for the tip! Update: Try disabling location services if you’re getting “unable to check for update” error. Thanks Irshad for the tip!

Update 3:

There is a new settings under Cellular (Settings -> General -> Cellular/Mobile Data) called Wi-Fi Plus Cellular. According to the note, this will allow apps having trouble with Wi-Fi to use 3G. Thanks Acidburnsn0w and Fozi for the tip!

Update 4:

The Privacy settings also includes new section for Twitter and Facebook as you can see in the screenshot below. Thanks Eric for the tip!

Update 5:

After updating to iOS 6 beta 4, you’re prompted to enter your Apple ID password for iCloud. It’s not clear if this was prompted due to the change in terms and conditions. Thanks Alan for the tip!

Update 6:

Apple has updated the help section (when you tap on the “i” icon) for Siri with the new features that are included in iOS 6 such as ask Siri about sports scores and stats, where to eat, what movies to see, to post on Facebook or Twitter. Thanks Cameron for the tip!

Update 7:

Siri local search (which is supposed to be available worldwide) seems to be working in Netherlands, Korea, Australia in iOS 6 beta 4. Thanks Henry for the tip!

Update 8:

iOS 6 automatically scales to taller 1136×640 iPhone display, which strongly indicates that the next generation iPhone will come with the taller 4-inch display with 1136×640 resolution. This is probably not something new in iOS 6 beta 4, but definitely quite an important discovery so we’ve mentioned it here.
