So I decided to upgrade my iPhone's OS to the 4.0 beta. I weighed the risks and the warnings... and decided I was too much of a techie nerd to pass it up.
Here's the process...
First, a few bullet point tidbits of info:
- iPhone OS 4.0 beta can only be installed via Mac, sorry Windows losers users
- You must update to iTunes 9.1 or you will have a disaster
1.) Retrieved my UDID
- Connect phone in iTunes
- Click on "Serial Number" and it will change to "Identifier (UDID)"
- Press Command + C (on mac) or Ctrl + C (on PC... though you can't currently run this install on a PC, FYI) to copy your UDID to your clipboard.
2.) Registered my UDID - Do not neglect this step or you will have a $500+ paperweight
- This can be accomplished a few different ways:
- Register as a Developer with Apple and pay $99
- Search "iPhone Beta 4.0" or similar on Ebay (be sure to check their feedback rating first)
- Commenters on most 4.0 beta blog posts are offering their slots
- Visit a site like: http://www.myiphoneactivation.com/
3.) Download the *.ipsw File
- Again, a few different options (make sure you have the correct file for 3Gs vs. 3G, Touch, etc.)
- Find a torrent file or conduct a google search
- Go here http://drop.io/beta1_8a230m (I used this)
- If you're a developer, download from Apple...
4.) Update iTunes to 9.1 - This is only available on Mac. Do not neglect this step or you will make lots of extra work for yourself.
5.) Create a Backup of your iPhone
- This allows you to keep all your pics, contacts, text message conversations, apps, etc.
6.) Install iPhone OS 4.0 Beta
- Connect your phone to itunes
- Hold option and click on "Restore"
- Select the .ipsw file you downloaded (do not for any reason unzip and rezip this file)
- Watch and wait as the OS loads... do not disconnect or force quit iTunes. Start feeling relief when the white bar begins to travel across your phone, this is a good sign that everything is working as it should.
7.) Get all your contacts and etc. back
- Connect phone to iTunes
- Right click (control +click) on the phone in the left hand pane and choose "Restore from Backup"
- Select the backup file you created in the beginning
- Wait. It may seem to not be working... keep waiting.
- When the Restore is complete you will receive and error message. (mine was 20) This doesn't seem to mean anything. Eject your phone and viola! You have everything that was backed up.
Should you need it, here's some troubleshooting:
- My phone locked up in the middle and now it is stuck in recovery mode. I have tried to restore, but it gives me errors and won't let me.
This is the saddest answer I've ever given. This happened to me (because I wasn't running iTunes 9.1) and the solution was to connect it to a PC running Windows XP (just my scenario, perhaps not an affective detail) and restore back to factory settings as prompted. Everything then worked as it "should."
Here are some screenshots of my 4.0 experiences...
- Hootsuite: will open, I can input my login info then it chokes over and over again. Never loads.
- Echofon: Worked great for first 24hrs or so. Now, will open, but as it tries to refresh most recent tweets, it crashes. None of my Twitter apps work.
- Planning Center Online: seems to be fully functional with one exception, it won't play music- but loads pdf's just find. Thankfully, it doesn't crash, just doesn't load.
- For the first hour or so I had to do a hard reboot 4 times, it seems to have settled now and I haven't had to reboot it once in the last 12 hours.
- Double clicking the home button brings up the multitasking (more like what you get with command +tab on a mac or alt + tab on PC)
- iTunes doesn't recognize the folder system and if you try to sync apps, it just erases all your hard work.
