Spoiler: GUIDE: How to install?

To get the beta over-the-air:

1. Enable Beta Updates (Settings > General > Software Updates > Beta Updates)
2. Make sure you’re signed into the right Apple Account
3. Select which beta you’d like to receive (public/developer beta)
4. Hit "Back" and pull down to refresh
5. Back up to a computer or to iCloud
6. Install the beta

If you no longer wish to receive beta updates:

1. Turn off the Beta Updates (you can also sign out of your Apple Account to reset this setting)
2. Wait for the next public release or follow the guide below to go back to a release build

Troubleshooting: If the beta doesn’t show up on your phone, try turning on airplane mode, then turning it back off, or restart your device.

How to install using a Mac?

1. You’ll need the Xcode beta itself or a MobileDevice.pkg somebody extracted from the beta (click with two fingers or control-click), then choose Show Package Contents. Go to Contents/Resources/Packages. - this will work on older Macs that do not support the latest macOS or Xcode betas)
2. Back up to your Mac or to iCloud in case you need to go back to another version
3. Hold down Option, then click on ‘Check for Update’/‘Restore iPhone...’ and select the IPSW file you downloaded from the Apple Developer site. Note: You must be connected to the internet to complete the restore.
4. Enter your iPhone passcode if you’re prompted to do so.

Notes/Tips:

• Always keep a backup in case you need to restore your phone
• Restoring wipes your settings and all data on your iPhone
• You only need to reinstall MobileDevice.pkg if your Mac stops recognizing your iPhone
• There is no MobileDevice.pkg equivalent to iTunes for PC which would require a new iTunes to support new/beta iOS
• Upgrading to a newer iPhone? You can update using your Mac before setting up the phone

That is not the beta we want. Also no change notes at all, what a bummer.

 

[krvld]

iPhone 16 series Modem Firmware from 1.60.02 to 2.02.01 – hype.

 

[xpxp2002]

iPhone 16 series Modem Firmware from 1.60.02 to 2.02.01 – hype.

Interesting. Usually major modem firmware version increments only happen between major iOS versions. Might be the same/similar firmware that's in iOS 26 B1.

Ususally newest iPhones modem firmware starts with an 1.XX. So they’re preparing for the iPhone 17 launch later this year.

Correct. It's just unusual for the major version increment to happen this early. It would typically happen in the iOS x.0 release in September.

 

[Stuipdboy1000]

Interesting, my 16 Pro is showing modem 1.70.01

 

[sbailey4]

Yep same version as in iOS 26 B1 2.02.01

[Edit] This is incorrect. The version is 1.70.01 for the iP16 series.

 

[Hamsterhjulet]

Correct. It's just unusual for the major version increment to happen this early. It would typically happen in the iOS x.0 release in September.

Could be a error or maybe they don’t plan to release 18.6 before new phones arrive?

 

[sbailey4]

They have already made the change for iOS 26 so assuming they just getting on with it now for consistency.

[Edit] Nope. The version is 1.70.01 for the iP16. This thread (page 1) was most likely copied from the iOS 26 b1 thread and as such has the carrier and modem firmware from that one copied as well. I have edited the iP16 in the spoiler to the correct version.

 

[christian.terra]

Interesting, my 16 Pro is showing modem 1.70.01

Same here

 

[teeshot44]

Interesting, my 16 Pro is showing modem 1.70.01

Same for my 16 PM

What Apple wants us to test in this beta:

(I'm going to skip this and MacOS, as I'm waiting for 26 to look a bit better and jump on that - hopefully B2 or B3.)

 

[Cu5co]

Same here

Same

Which beta are you waiting for?

Yeah it is!

Ignore me I’m an idiot

Seems iOS 18.6 beta 1 adds a new Junk Messages in iMessage if you have Filter Unknown Senders enabled:

 

[Artemiz]

Seems iOS 18.6 beta 1 adds a new Junk Messages in iMessage if you have Filter Unknown Senders enabled:

Not on my 13Pro

 

[iOSBry]

Not on my 13Pro

Did you confirm via the All Filters view in Messages (and you have Filter Unknown Senders enabled)?

 

[Artemiz]

Did you confirm via the All Filters view in Messages (and you have Filter Unknown Senders enabled)?

I've always had the filtering ON and it's just the same old with known and unknown. No Junk section.

 

[iOSBry]

I've always had the filtering ON and it's just the same old with known and unknown. No Junk section.

Well, it wasn’t there for me until I installed 18.6 beta 1.

 

[tosbsas]

hm, wird, 15 pro max is 2.70.01 not the number mentioned in the post

 

[Hamsterhjulet]

Seems iOS 18.6 beta 1 adds a new Junk Messages in iMessage if you have Filter Unknown Senders enabled:

Nice little find! It’s indeed new on iOS 18.6. It seems like the last major iOS 18 version focuses on bug fixing.

 

[13paul13]

I’ve updated to this on my main iPhone (15 Pro) and expanding notification stacks on the Lock Screen is much smoother. It was really janky in 18.4.1 which I upgraded from.
