iOS 5 beta 4 is an OTA update... if you can connect

It looks like the just-released iOS 5 beta 4 is an OTA update, with Apple pushing the bit-differential/delta file over the air, over 3G... if you can connect. Lots of people can't, according to Twitter, and are getting "Try Again" errors. When it does work, however, it seems to work well.

Also, many of you are telling us you're having no luck updating via iTunes or Xcode, with "this device isn't eligible" errors cause all manner of frustration.

If you get your update on using either method, let us know!

iOS 5 beta 4 is an OTA update... if you can connect


iPhone 4 - Mine is stuck at the end with '<1 minute remaining' message for most of the download, have tried quitting settings and restarting the device to no avail. Progress bar seems to move forward then rolls back in a loop (70% - 90%) - could be validation. Waiting...

Mine has said <1 minute for quite a while and I am using a wifi connection. My status bar never said anything other than <1 minute either. Any advice?

Glad I'm not the only one think it's because the server is being slow bit like the first bit of the download. Should be ok soon.

Is anyone experiencing the inability to edit their contacts?
Also bank of america app closes all the time
Skype is not working in multitasking

yes to all of the above, some apps are not acclimated to work on ios 5 yet so they will be glitchy.

It's all done wow It's just the servers that are slow but it's the first time Apple have ever done this so it will be slow look at Lion.

Its version 9A5274d and GSM on AT&T code is 10.2.6
If u r getting verification error then try and restart the phone it should work. It worked for me.

Post-Install notes: Much less lag in my opinion. Mail notifications are stable. I had issues with the previous builds of not always displaying. When unlocking the phone and directly opening to a text message, it no longer locks up for a few seconds. Overall, I like the process, albeit a little slow.

I was waiting for beta4, didn't do the 3rd but i now just did to try the OTA option and worked the minute i was done restoring to beta 3. Sweet deal!! Does netflix work now?

It took 5-6 tries but downloaded the software in about 10 minutes and installed without an issue. I was actually very impressed how smoothly it went just being released.

My iPad was very buggy under beta 3. Almost unusable. I just updated to beta 4 OTA, and I don't feel that "new beta freshness" you get with a clean install through iTunes.
Is this now like Mac OS? A fresh install will yield less buggy results than a delta OTA update?
Anyone try both?

Worked fine for me on first try. Walked away for an hour and it was like nothing changed. Much more smooth in my opinion

Would it mess with a jailbreak? My jailbreak is the only thing that activated my phone and iPad

I just installed on my iPhone 4. It took about an hour to download on a 3G connection.
Once downloaded it said that it would not install as my battery was below 50% and not on power source. I plugged in and then installed, took about 10 mins.
All seems ok, some things noticed, photo albums are gone and you can't forward an email with an attachment.
Everything else seems ok.

2 different experience:
1) on iPad 1 like most others I initiated manually the update, it got stuck in the downloading < 1mn for a long while (more than 30mn but it was done when I went back from shopping)
2) on iPhone 4 I didn't ask for anything then got a notification that the update was available and when I went to the settings it was already downloaded (must have done it automatically) and install could be done without plugging it in and fairly quickly (10mn I would say I didn't time it )
