You do realize you've cut your credibility by about 90% with this comment, right? "I've just downgraded back to iOS 4." Care to elaborate how you did that?

As the release notes say: "Devices updated to iOS 5 beta can not be restored to earlier versions of iOS. Devices will be able to upgrade to future beta releases and the final iOS 5 software."

That's right, it's irreversible. (I can corroborate this.) So you've determined iOS 5 isn't ready for prime time (obviously, it's a beta), say it's very buggy but can't elaborate what the bugs are, and somehow managed to hack a way to downgrade your iPhone to iOS 4, even though it's not possible.

How rude. What's your problem?

If you are publicly calling me a liar, then you may want to rescind that comment. You have absolutely no idea who I am of course, but I'm a professional developer who is happy to post under my real name and not an alias, has worked with the iOS SDK since it originally launched and am proud of my reputation amongst my peers. I await your public apology.

You can corroborate all you like; I certainly didn't imagine downgrading to iOS 4 this morning...all I did was:

a) Download the iOS 4.3.3 restore IPSW
b) Open the Xcode organizer and restored my phone to using the ISPW
c) Launched iTunes to re-activate
d) Restored from the backup I took before I upgraded last night.

YMMV, naturally, but it worked for me no problem. Obviously, I had already investigated this and spoken to others to see what success they had in downgrading before proceeding.

My post was nothing more than a warning to those who were thinking about installing a buggy beta that isn't ready to be used on an everyday phone. Clearly, I can't go into specifics because unlike some developers on here, I prefer to respect the NDA that I agreed to.

EDIT: just to clarify, regarding downgrading, and to add to my YMMV statement above: I have only tested downgrading on an iPhone 4. Results on any other device may vary.

If you've not come across bugs, then you haven't tested it enough. It's not ready for prime time. At all. I've just downgraded back to iOS 4. Apple's advice to only install this on development/testing devices is sound. I wouldn't recommend it for any other purpose right now.
I didn't say I haven't found any bugs, I just disagreed when you called it 'very buggy'. You keep warning people not to download it on their every day device. I'm telling people I've done exactly that with zero repercussions.

So what's the general consensus here? I read on a thread on the Apple Developer Forums that third-party apps don't launch at all. This true?
Not true. All of my 3rd party apps are working.

I am and will continue to warn people not to install it on their everyday device, just the same as Apple do. If you rely on your phone on a daily basis you may want to think twice about putting software that is clearly several months away from prime time.

As an iOS Developer running iOS 5, I can confirm that a) it's very very buggy (these betas always are) and b) it is possible to go back.

Bugs - leaving the iPad 2 in standby for more than 5 minutes results in it needing a hard reset, various memory leaks on both iPad and iPhone (very sluggish response even on an iPhone 4 sometimes), and yes, a lot of 3rd party apps crash on startup. However, it is stable enough to use as a phone, for email, for messaging, and for Twitter (on the iPhone at least - the iPad 2 issue is a bit harder to get around). Oh, and there are no background wallpapers... that sucks.

Downgrading - it has always been trivial to downgrade betas to the previous stable release, Apple just always put a load of warnings up in case you accidentally brick your iPhone. Evidently you cut your credibility by not checking out with somebody who knows what they are doing...?

Just a helpful tip - respect what other people say and maybe they'll respect what you say. No need to call someone out as a liar because you were misinformed.
 
Everything works on my iPad 2 but any App that I download from the App Store crashes upon load. Even official Apple apps.

iPad & iPhone has no wallpaper selection. I love the new notifications though! So clean!

This is Beta software, try it at your own risk. BTW, it's just a phone. If you are scared to test it then it's not for you.
 
bugs/crashes

A few things to be mindful of running the beta on iPad2 CDMA -

Home Sharing music and movies is definitely buggy - as mentioned by others.

The Weather Channel, Air Video Netflix, Hulu Plus, iHeartRadio, and HBO Go are all not working - meaning they crash instantly or do not stream video.

Some RAW image files will display as pixelated for the thumbnail but work correctly when selected.

Some images saved to the camera roll crash the Photos app when selected

Split keyboard when used in iMessage sometimes will cover message thread, until dismissed and then summoned again by tapping the text entry field.

Airplay Mirroring is AWESOME. However, it still will not let you get Hulu Plus to output onto an Apple TV 2.

Haven't got to test many games or anything else yet (still have about 130 apps to go!) but all of the Apple apps appear to be working fine.

Oh, and Facetime video quality is MINIMALLY better on iPad 2.
 
I have a problem.

E-mail won't send. It just does nothing when I hit Send. I didn't even realise it wasn't sending until I tried to test it and went into Sent mail and none of my previous real emails had sent!

That's using the Gmail account option with Google Apps e-mails.
 
So far I can't see it being like horrendously buggy, but yes it is still for sure not ready to be released.

The biggest problem I find is that my email won't pop up in notification center or on lock screen. Anyone else have this problem?? :confused:

Been running it since day one. Buggy? yes, but not the doom and gloom you may hear. Again, just be prepared for things to not be completely polished and some apps not working. Most of my every day stuff has been working just fine.

For emails in the notification center, just make sure you have that turned on. You have to configure what you want in the notification center and on your lock screen. THere are some defaults but just double check. In settings, you can also tap "edit" and change the order in which things appear in the list.

Have fun!
 
IT IS STABLE ENOUGH FOR DAILY USE

Good idea to do after you restore to iOS 5, is to do a hard reset. It'll fix any battery issues and eliminate the lagginess almost all together.
 
Has anybody installed it on a 3GS ?
I'm wondering if it could be worth it to find an used 3GS on ebay and use it as a development unit.

From what I've heard from those who have installed it on a 3GS, it seems to work fine. Can't say much more than that though, unfortunately.

On a slightly unrelated note, the sync icon in the status bar will NOT go away on my iPhone 4, and every time I restart the phone I get a "Some items not restored" popup that says "This content is not currently available for re-download". Nothing I've tried has gotten rid of this, so I am tempted to chalk this up as a bug. Still, it's been running amazingly smooth besides that minor annoyance, and even better than 4.3.3 in some aspects!
 
yes it is stable enough. Some bugs are dictionary is not opening. no wallpaper to select.In safari when u link page put address & click on send it crashes. No wifi sync. Byline also crashes some time.In photo there is no Places tab. i am also thinking to downgrade is there simple way like putting in DFu mode & restoring 4.3.3 ispw.

I don`t have Xcode organizer is there any other way to downgrade to 4.3.3 I have the restore 4.3.3 IPSW

I went through all those options... I'm wondering now if it's because I have my Gmail set up as a Microsoft Exchange push account instead of the Gmail fetch setup?

Thanks for the help tho and I'll keep trying to figure this out!!! :D
 
Do you have to use xcode and set your phone as "use for development"? I am trying to install ios 5 on my iphone 4 and whenever it tries to install it says there was an error.

Just signed up to be a developer two days ago for ios 5

Use Xcode to set it up for development and to install it.
 
I installed on 3GS and things are running fairly well. Calendar isn't syncing (other than birthdays) but my 3rd party apps are running fine (so far). The camera doesn't seem to work using the vol toggle as a shutter switch but it does open up camera from the lock screen using dbl home.

Per earlier post regarding sending mail. I had this trouble initially and deleted all accounts and added them. Resolved mail issue. Avoid working with iCloud as it seems to affect syncing at this point.
 
IOS 5b and Jailbreak?

Has anyone been able to successfully Jailbreak an iPhone 4 running ios 5b?
Thanks

iOS 5 has been jailbroken as said by several of the developers currently at WWDC but no jailbreaks will released for at least a while. Probably not until the final version of iOS 5 actually releases because it's not worth it for jailbreakers to spend their time on it until the real iOS is available. Lots of things change between versions of the developer iOS's as well.
 
I loaded iOS 5.0 beta on my iPhone 4 just as I did for iOS 4.0 beta for daily use and it works fine, sure there are a couple hiccups but nothing that can stop me from using new software!

Settings > Notifications > Mail > tick "View in Lock Screen"

You might also need to set the Style to "Banners", I'm not sure.
 
will itunes 10.3 sync with iOS 5 beta, or do you need to upgrade itunes to the 10.5 beta as well?
