Apple posts original iPhone to iPhone 3G upgrade how-to

Apple has posted a new support article explaining how users can replace their original first-generation iPhone with an iPhone 3G using the same carrier. The article, titled “How to replace an original iPhone with an iPhone 3G,” says, “If you follow these steps to backup your original iPhone first, and then restore the backup to your iPhone 3G, your saved SMS messages, email accounts, photos, notes, and other personal settings will be present on your iPhone 3G.” According to the six-step process, US-based iPhone customers will not need to swap the SIM cards from the original to the iPhone 3G, while users in the United Kingdom, Ireland, Germany, Austria, and France can use their original SIM with the new handset. Apple will launch the iPhone 3G in multiple countries worldwide on July 11.
