Unfortunately for some iPhone 3G users the iOS 4 update did not go very well. Reports have surfaced that the new firmware has problems running on the older hardware. The good news is that Apple is working on iOS 4.1, which will alleviate many of the problems with iPhone 3G compatibility.

In the meantime, upgraders have experienced premature battery drain and excessive heat coming from their devices. Performance has slowed to a crawl for some users as speed issues dominate, with many unable to run simple tasks without a headache.

Apple has launched FaceTime video calling with every iPhone 4. All that's required is a Wi-Fi connection and a person on the other end of the line running the same setup. There are many things you can do to get the most out of your FaceTime calling experience.

Yesterday, only 2 weeks after releasing iOS 4.1 Beta 1, Apple seeded the second iOS 4.1 beta to iPhone developers. The only official iOS update released thus far (iOS 4.0.1) was a fix for signal bar problems widely reported by new iPhone 4 owners. Though the signal bar issue and the related "death grip" fiasco has gotten an incredible amount of press, the issues this latest iOS update is reported to address may have a far greater impact with iPhone owners.

Despite ongoing manufacturing and inventory problems, Apple is forging ahead with its global rollout of the iPhone 4. Friday July 30 will see the introduction of iPhone 4 smart phones in 17 additional markets. Apple first launched the iPhone 4 on June 24 in the US, with cellular service exclusively provided by AT&T Wireless.

Over three million iPhone 4 units have already been sold. Apple recently announced it was not making the white iPhone 4 model available until later in 2010 due to manufacturing difficulties. The white version was previously expected to hit shelves at the end of July. The next batch of countries slated to receive the iPhone 4 include the following:

Apple fans are still waiting for a white iPhone 4 release date as Apple claims to have encountered manufacturing difficulties. The device was delayed twice, even after Steve Jobs announced white iPhone 4 availability would come by the end of this month. It could be that the press conference about the iPhone 4 antenna has more to do with the white iPhone delay than the painting process.

Apple is offering iPhone 4 owners a free case to alleviate antenna reception problems until September 30. Speculation is now rampant that the company will use this time and the already long white iPhone 4 delay to implement improvements to the antenna design. A change would make it unnecessary to offer free iPhone cases to owners of the white model, especially if the white iPhone 4 release is delayed until October 1st.
