Christmas comes early this year, the iPhone 4 is near! With the iPhone 4 comes the operating system update now called iOS 4, which will also bring new features for iPhone 3G(s) and the latest iPod touch generations.
Since I am waiting for a white iPhone 4, I thought in the meantime, let’s upgrade my iPhone 3G to iOS4. Let me take you on a trip!
First of all, relax – get some tea, beer, … whatever you like and free some time to do the upgrade. Depending on your iPhone (iPod touch) model, your connection speed and available download bandwidth from the Apple server, plus your data size, it will take about from 30 minutes to 2 hours.
Go into airplane mode, take a manual backup via iTunes, save your settings, call your mum, sync all, export your sales from the iPhone into the library, have a tea, click slowly. Then hit the update button to install 4.0. Click through the windows, accept here and there and be happy when it starts. Now might come the tricky part, if the upgrade makes again a backup, and the progress bar hangs for over 30 minutes at two bars, hit cancel. Start again and in the 2nd round, it worked here. Be patient with the progress bar, if you have e.g. 12GB data installed, that will take some time… Time for another tea.
After a while your iPhone will reach its blackout point, wants to be activated again, enter your sim code, when it wants to be plugged into iTunes, unplug the cable, drink some tea, and plug it back in. When the backup starts to rebuild the data, simply wait, the iPhone might reboot and then start to rebuild also all your personal data…
One minute after I connected to the mobile network, I got a SMS from the German Telekom telling me it wants to upgrade the phone driver, hit upgrade. In the settings I read Carrier T-Mobile 7.1 (was 7.0 before).
The new folders are good Feng Shui, cutting down my home pages to only 3 (was 10+). Happy upgrading!
