How to Restore iOS 5 on iPhone 4?

Dear Jaxov, I am wondering if I can install the new iOS on my iPhone 4. I am currently using iOS 4.3.3. Is the new iOS 5 firmware ready to use with no problems? A friend of mine have an iPod Touch 4G running on iOS 5, I also want to install iOS 5 on my iPhone.

Hello Richard, Yes you will be able to install iOS 5 Beta 1 firmware on your iPhone 4. Regarding with iOS 5 “problems”, since it is still in beta version it is expected to have some bugs. Additionally, it is also worth noting here that iOS Beta 1 is intended for registered iOS developers for testing purposes only and iOS 5 can be downloaded at the Apple Developer Center for those who are enrolled in the iPhone Developer Standard or Enterprise Program. If you have an account in either of these two programs, then you can access all the beta bits signing into Apple Developer Connection or iOS Dev Center using this link. But if you don’t have an Apple Developer account, you can still install iOS 5 on your device by searching for “leaked iOS 5 download links” in the web. Check out some notable features of iOS 5.

If you have downloaded iOS 5, then simply restore it on your iPhone. Don’t forget to back up your device before restoring. To restore, all you need to do is launch iTunes (download the latest version of iTunes) and connect your iPhone into your computer. Then select your iPhone under Devices, then select Summary tab and then Restore option. Now, iTunes will prompt you to back up your device, ignore it if you have backed up your device. Then select Restore option when iTunes prompts you. Now, wait for iTunes t complete the restoration process, the iPhone displays the "Connect to iTunes" screen. Keep your device connected until the "Connect to iTunes" screen goes away or you see "iPhone is activated." If iTunes does not have an Internet connection, you cannot complete this step. Now, restore the previous set up of your iPhone by restoring the backup you want for your device.iOS 5 Features
