Apple iPhone 3gs iOS4 upgrade experience

by Savan Thongvanh June 21, 2010

I just wanted to do a quick hit on my upgrade experience for my iPhone 3gs.

I came home for lunch today so I could do my upgrade.  I hit up iTunes PRAYING that I wouldn’t get queued up for download like last time.  Also in my prayers was that after going through the trouble of downloading that I wouldn’t get the dreaded “cannot contact activation server” error.

Well, it looks like this time I lucked out.  My iOS4 download only took 17 minutes.  I’m seeing people tweet now that the download is taking upwards of half an hour.   No problemo there.

After I got the download iTunes started to backup my iPhone.  Thank you.  The backup status bar seemed to sit on 2%ish for EVER.  After about 15 minutes of looking like it was doing nothing it jumped to about 25%.

The rest of the install included expanding the download and restoring my data from before.  All in all it took me about 50 minutes to upload 17 for the download and about 35 for the backup and install.

Now on to playing around iOS4 and seeing how gimped it is on my iPhone 3gs.

More to come on the features and limitations on the 3gs.

UPDATE: This article is actually about updating a 3G, not 3gs but all info is still applicable.

UPDATE:After trying to update a second iPhone 3G I got all the way through the install process and got the activation problem that seems to be common.  Servers are evidently swamped now.  I’ll try later tonight to upgrade the 2nd phone.

  1. Why is my ios4 upgrade on my 3g iphone Restoring everything from, Applications to Music and Video. I don’t remember this being done on previous Software Updates. Is this been happening to everyone else??

  2. Hey Niel, yes that happened to me too. I don’t remember that happening before either. I’d *speculate* that some of the code or files had to be ported to ios4 but that’s not confirmed.
