The recent announcement of iPhone OS 4.0 beta brought some interested features for developers. I’m still pretty new to iPhone development and was trying to figure out how to update my phone. Below are the instructions once you’ve downloaded the IPSW file to update the firmware.
Installing iPhone 4.0 beta on the iPhone
- Make sure to have downloaded the iPhone 4.0 beta firmware that relates to your iPhone (e.g. 3GS).
- Extract the firmware IPSW to a folder.
- Connect the iPhone to your computer.
- Get the UDID registered on the iPhone Developer program. Provisioning Portal > Devices > Add Devices
- Open iTunes and click Restore while holding the Shift key (for Windows) or Option key (for Mac).
- Locate or browse to the firmware IPSW.
- Wait for iTunes to unpackage and install the firmware.
UDID can be view in 2 ways:
- In Xcode, navigate to the ‘Window’ drop down menu and select
‘Organizer’. The 40 hex character string in the Identifier field is your
- OR In iTunes, select your device in the ‘Devices’ section and navigate to
the Summary tab. Click on the Serial Number label to reveal the
Identifier field and the 40 character UDID. Press Command+C to copy the
UDID to your clipboard.
I’ve been holding off starting iPhone development for some time. The recent iPad announcement coupled with the lack of progress in the Windows Mobile world has lead me to making a decision to try out a new platform (finally). With the purchase of the MacBook Pro, it’s time to dive right in and start from basics again. I first started in Palm development (horrors of C++), moved on to .Net (C#) and now with Objective-C, it seems “C” is the common thread linking my mobile development path.
Time to dust off the great “C – How to Program” and gettting started with the first book “iPhone SDK Development“!
I remember seeing my first Apple Macintosh at cousins house at a very young age and being amazed about the green glowing text on the screen. That sparked me off on the journey that has me fascinated with technology. For some reason, I’ve yet to own a Apple product in my life! So its rather prescient when a Facebook quiz which asked “Are you a Mac or are you a PC” results in a Mac! When Singtel sent the invite to pre-register I didn’t give it much hesitation since it looks to be a great platform for development and a capable smart phone (At last).
Counting down to welcoming Apple to the bunch of Windows machines in the home. 2 days to go!
Will also be saying good-bye to M1 on Friday. Have been with them since my first Nokia phone in 1998.
