Last month, Apple had introduced iOS 4 for iPhones and iPod Touches. This new OS update was actually meant for the devices that can handle resource intense applications.

Apple had also specified it in their release conference. iPhone 4 and iPhone 3GS can run iOS 4 without any problems, but iPhone 3G was not fully compatible with updated iPhone OS.

Even though Apple’s iOS 4 has been designed to work with iPhone 3G, users are not very much impressed with its performance on the phone. Several iPhone 3G users have faced the lagging problem with this OS and reported it on different online platforms. Now, the company has assured to work on the iPhone 3G issue.

It’s not sure when Apple will release a proper fix to this problem. However, there are few things that can help you improve the performance of iOS 4 on iPhone 3G. You can try these methods on your phone.

I have seen many iPhone 3G users complaining about the sluggish iOS 4 experience on their phones. Apple team has tried their best to bring iOS 4 on iPhone 3G, but the phone is very limited in terms of the requirements of the new iPhone OS.

There are few things that one can do to speed up the iOS 4 on iPhone 3G. Of course, there is no guarantee that your iPhone 3G will work faster after using these tricks, but it will certainly make your phone more usable with iOS 4.

How to improve iOS 4 performance on iPhone 3G?

1. iPhone 3G Cold Death

In layman’s language, iPhone 3G cold death is nothing but a different way of booting your phone.

To put your iPhone 3G in cold death, press and hold the “Sleep” and “Home” button simultaneously for about 10 seconds. It will take some time to reboot your iPhone, so don’t worry about it.

This method really improves the performance of iPhone 3G running on iOS 4.

2. Remove Unwanted Apps

If you are using 100-200 apps on the phone, it will definitely decrease the iOS 4 speed on your iPhone 3G. So, it is recommended that you should remove the unwanted app from the phone.

3. Remove Shadows from Icons

I’m not sure about this method, but apparently it has worked for those who have tried it on their iPhone 3G. Just remove or rename the shadow file.

I have not tried this trick on my own. So, if you are willing to try it, try it at your own risk.

4. Delete Language Packs

Apple provides multi-language support on iPhone, but most of us only use English language on the iPhone. You can delete useless language packs from your phone to free some memory. Watch the tutorial here.

These are the few tricks that will help you boost the performance of iOS 4 on iPhone 3G. As I said earlier, it will not work for everyone. If you do it correctly, it will give you good results.

We have been reporting about Android operating system being ported to iPhone. The hacker has completed most of the work, and has released Android Port for iPhone 3G.

Even though Android OS is ported to iPhone OS, some features will not work properly on your iPhone. Some enthusiasts have also found glitches in Android OS and they have noted that Android powered iPhone consumes lots of battery.

If you try Android port on your iPhone 3G, battery will completely drain in an hour or so. At this moment, the Android port for iPhone is not fully developed. It’ll need some more time to enjoy the complete Android OS experience on iPhone.

I would not recommend you to try it on your iPhone 3G. In case you want to take the risk, use the guide written on PC World to perform installation operations.

David Wang aka Planetbeing has delighted everyone once again with his work on Android OS for iPhone 3G. Yes, the hacker has finally completed the development process, and solved all major issues in this task.

David has previously hacked iPhone 2G to run Android 1.6 operating system. Many enthusiasts tried this OS on their old iPhone 2G devices, and they are pretty much amazed with the efforts of the hacker.

Android on iPhone 3G supports most of the features including Wi-Fi and SMS, but important call features is not yet delivered on the phone. As usual, he has posted a video to show Android OS working on Apple’s iPhone 3G. Watch the Android on iPhone 3G video after the break.

Although the hacker has not mentioned any release date, it should be available soon for end users.

In last week, we have seen a video of Android operating system running on iPhone 2G phone. The hacker who had developed this trick has now successfully added multi-touch support for Android on iPhone 3G.

The hacker has written a piece of driver code for Zephyr2. It basically brings multi-touch feature on the iPhone. Apparently, Apple also uses this driver on their iDevices, which mainly includes iPhone, iPod Touch and newly launched iPad.

Android OS is now almost ready to run on iPhone 3G, but there are some major issues that need to be solved before moving ahead in the process. If Android OS runs appropriately on iPhone 3G, it’s quite possible to run it on iPad tablet. However, it will require much time and development to get full featured Android OS for iPad models.

For time being, watch the following status update video of Android on iPhone 3G.

iPhone Dev team has released jailbreaking tool redsn0w 0.9.5 for iPhone OS 4 beta, but some developers have reported SMS and 3G data failure issues.

Musclenerd, Dev team member, has now released redsn0w 0.9.5 beta 2 to fix these issues. In order to use this beta version, you will have to restore iPhone OS 4 beta firmware.
