The latest iOS 4.0.1 update from Apple is said to fix the antenna issue of iPhone 4 problem. Many iPhone 4 users experienced antenna issue when they talk on the phone. This update will benefit mostly iPhone 4 users. iPhone 3GS and older model still can upgrade to latest version but I hardly find a reason to upgrade it unless it has better upgrade on existing iOS 4.0 which benefit older models. The concern would be security update which apply on latest iOS 4.0.1.

Hope this update will fix the iPhone 4 issue in the market since it is great and gorgeous phone. It could become a perfect smart phone at this moment if antenna problem did not exist at all. Have you upgrade to latest iOS 4.0.1?
