The social gaming feature namely the Game Center App will not run on iPhone 3GS and second Gen iPod Touch confirmed Apple. Earlier the buzz was set by the company by announcing the new social gaming feature which would run on any iOS 4 device. All existing iPhone 3G, 3GS and second Gen iPod Touch upgraded to the new OS to go gaming as soon as Game Center Beta version hits the market.

The possible reason that Apple has dumped the older versions of the device could be due to various negative reports on the iOS upgrade. Various problems have been reported by iPhone 3G and iPod touch users about problems in upgrade to iOS 4. So you have got another reason to buy the new Apple iPhone 4 if only you haven’t got one. The Game Center Beta is being considered as the next big thing to kill the portable gaming consoles by the entire gaming industry.

Apple has released iPhone OS 4 in beta preview for iPhone Developers with paid account. But here is a little problem if you’re an iPhone 3G user. iPhone OS 4 works well on iPhone 3G and supports all the new features except for ‘Multitasking. It’s been said, “iPhone 3G has incompatible hardware to support Multitasking feature”.

If you’re an iPhone 3G user you will probably have to wait for some more time to experience multitasking. There’s a new iPhone coming up this summer. It would also mean iPhone developers who are creating apps based on this multitasking feature would serve only users with iPhone 3GS.

Your iPhone 3G will be getting the rest of the cool features offered by iPhone OS 4, like Wallpaper, Folders etc. Keep checking back this place to know more about what iPhone 3G & 3GS are getting in particular.

However, iPhone 3GS has full support for all the features that have been shown off at the preview event. You can refer to our earlier post to read more about all the features of iPhone OS 4 that Apple showed off in the preview event.

Many of my friends woke up to a rude shock when they found that their devices updated to iPhone OS 3.0.1 were not supported by iPhone SDK 3.1 Beta 3 for development.

If you too are experiencing the same problem, here is the solution to continue iPhone development with iPhone SDK 3.0 for your iPhone running iPhone OS 3.0.1.

1. Log-in to your MAC with an Admin account and launch the Terminal application (You will find it in /Applications/Utilities)
2. Copy and Paste the following line into the Terminal window
ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0\ \(7A341\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

Note: If you have not installed iPhone SDK 3.0 in the default location “/Developer”, replace the “/Developer” directory in the above line as appropriate.
