Backup Plan

So many problems with my update.

Eventually, after the backup failed several times, I removed all songs, videos, apps, photos, everything from my iPhone, then did the update to iOS4, then put everything back on. And even then the update itself took about an hour.

But that seems to be the best way to do it if you're having backup problems (though you may lose some data associated with your apps in removing them). :rolleyes:
 
My experience with iOS4 so far:

Updated iTunes to v9.2, and Safari to v5. This involved a 120Mb download,
and took about 30 mins to download and install.

Disconnected from the internet, connected my iPhone, and let it backup and sync itself. (took 2 -3 mins, I tend to do this every week or so)

Reconnected to the internet, and after iTunes had connected, and offered me iOS4 as a software upgrade, I pressed the "Upgrade Software" button.

It took 20 mins to download iOS4 (378Mb), good for my internet connection (O2 Mobile Ireland)

It loaded into my 16Gb, 4 month old, 3GS phone with 8GB of music and a few aps on board, in 5 mins!

The iPhone then rebooted automatically.

I had to reenter my SIM card password, and then the phone returned to life.

So far everything works normally, all the data in my contacts, notes, and the music in iPod has been retained, and all my
aps work.

So far for me a painless upgrade.

The iPhone manual on Apples web site is still for iOS 3.1, I guess we will have to wait for the iPhone 4 launch to get a manual update to see what we can realy do with the new OS.
 
Updated my 16GB 3G with a late 2009 macbook pro. Worked fine, took 2 hours or so to do the backup, restore, and replace the data on it - about 14GB worth.

Works fine, you can tell it struggles with some actions though. Bit bummed about the lack of home page backgrounds, even though I've not had them before. haha!

Bring on the iPhone4 next month. :D
 
Download took 3 mins for me on a 100mbs connection. I love being in Singapore . . . seems like Apple has peering here for all their stuff. :)

Backup went smoothly, took like 3 mins. Installing now . . .

I have a 3G.

The whole install took about 20 mins in total, including the time to copy back my music etc. Very smooth. All of my installed apps would not launch - only the apple apps launched - until I restarted the phone after the update.

No buggy weirdness as far as I can tell, and performance is slightly snappier than previously with 3.1.3, but no big difference. I've had this 3G for a long time, and I remember that performance was really fine (fast) with the originally installed 2.x OS, terrible with 3.x OS, and basically somewhere between terrible and fine with iOS 4 so far.

My (conflicted) impressions:

<fanboi>
Wow, it's awesome! Look, folders! Holy crap, look at how beautiful the new mail and other icons are! Awesome new calc icon! Digital zoom! Different layout in iPod player app! * takes heart pill *

* searches for differences *

* still searching *

* checks about page to confirm that this is not 3.1.3 *

Wait, what's different?

I have an iPhone 3G 16GB and have 12GB free memory.This is what happened to me

June 20, 2010(Monday 1pm)- I started to download the iOS4, it only took 20 minutes. After that, I started the update for iOS4.
Just like everyone here, the phone is been plugged for almost 2hours for backup, but only 5% on the progress bar. so I stopped the back up and try again.
Around 4pm the same day, I tried to update it again. still the same and took me 2hours again and still no progress that much. Clicked the stop button again.
Before 7pm the same day, I tried it for the last time but still failed.

June 22, 2010 (Wednesday 10:30pm)
These are the steps that I did.
First I right clicked my iPhone and clicked "BackUP"
then I clicked "Restore" button
it only took me 30minutes to restore and update the whole thing, and 20minutes more to put sync my apps again.

*I put my phone in airplane mode when I updated it today (June 22, 2010), after the restore and update (it now runs on iOS4) there's "NoSignal" and I just simply went to "settings" then clicked "airplane mode from off to on then on to off again" and it worked.

at last I finally updated my phone, I was about to loose my cool. But anyways my phone runs very smooth and very fast.!
 
I think that our iPhone are still somewhat stuck in the recovery mode loop. :( Have to know more commands to break out of the loop. :(

this just happened to my wife's 3G, it's effectively dead now. It won't break out of the recovery loop, and it is NOT recognized by iTunes now. I have no idea what to do
 
ios4

got mine sorted last night for 16gb 3gs, all went fine, backed up phone, downloaded software updated phone and synced it all in all took bout 45 mins and everything was fine, like the new software and groups is v handy.

only thing i would say and it is a spotify issue not ios4 is i was hoping spotify would play music when app not opened on the new multitasking but it doesnt, it stops playing music so hopfully a spotify update soon

all in all happy and would like the new phone but am contracted till may 2011 so have to wait

when is ios4 for ipad due

Sorry, but this process is taking 2+ hours on my 16GB iPhone 3G - and that's not counting the time it tried and iTunes crashed. The download of the software upgrade itself went fairly quickly.

Over 2 hours to update a phone??? Huge FAIL on Apple this time around. This may not finish before I need to checkout of the hotel I'm in. And I thought downloading the software on a slow hotel network while everyone else in the world was doing it would be the hard part.
 
I've been running OS 4 since launch. Aside from the long backup, the install went well. Since I can't upgrade my phone until January, it's been worth the upgrade. I like the background option, drag and dropping pdfs into books in iTunes, and the app folders. I haven't really noticed a difference in speed, although sliding the app pages does seem snappier, and haven't noticed any less battery time.

My main want/disappointment, is since I don't have iPhoto, I wish I could drag a photo ontop of another to create a folder in photos like in apps. Maybe that can be included in the next update.

If you have save your shsh file for 3.1.3, you can use ireb frem ih8snow.com to get out of the recovery mode loop then downgrade the phone and jailbreak it.
