iPhone 3G upgrade process
Apple this week began posting information for iPhone users intending to update their device to the new iPhone 3G. A new support document explains how to replace an original iPhone with an iPhone 3G using the same carrier: "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," the company noted. The instructions indicate that iPhone users in the US will not need to transfer their SIM card (a new one will be provided with the iPhone 3G) and describes how to transfer settings, personal info, SMS messages, and other data to the new device using iTunes' backup iPhone feature. The document confirms that the iPhone 3G will require the yet-to-be-released iTunes 7.7.
In addition, it notes that the US is the only country in which the iPhone 3G will come with a pre-loaded SIM card; in other parts of the world, users can use their original iPhone SIM and while the document still references the current "erase" function, iPhone 2.0 software is expected to include a more advanced and secure data wipe function.
