iPhone 4

Ever wondered if you could swap out the micro-SIM card in your iPhone 4 to get free data from AT&T on the iPad 3G? Well stop wondering. Turns out a simple change to APN settings on the iPad makes it possible to use the iPhone 4 data plan on Apple's tablet. No jailbreaking or SIM card modifications required.

As the helpful folks over at TUAW explain, the procedure is quite simple but does involve many small parts. Carefully use a SIM removal tool or paper clip to open the SIM trays on your iPhone 4 and iPad 3G. Don't mix up the trays and keep track of which card came from which device! When the iPhone 4 micro-SIM is safely inside the iPad 3G, all you need to do is make a change to the APN settings on the iPad.

Watch out Apple, Fring has FaceTime in its sights and has launched a new version compatible with iOS 4. What this means for owners of the latest iPhone is they are no longer restricted to Wi-Fi only video chatting. Not only does Fring enable 3G video chat, the company is offering their software for multiple smartphone platforms.

Unlike FaceTime, which only allows video chat between two people who both own the iPhone 4, Fring makes it possible to video chat with anyone running the software and with those running Skype. Currently Fring is available on Android and Symbian phones as well as iOS 4.

Apple now claims an error in the iPhone 4 firmware is responsible for the dramatic drop in signal bars some have experienced when the device is held a certain way. An update for iOS 4 will be released in the coming weeks to address the problem, but in the meantime several lawsuits have been filed against Apple over the issue.

The most recent suit was filed Friday in the Northern District of California and accuses Apple of false advertising, breach of warranty, and unfair competition among other complaints. The plaintiff, Steve Tietze is seeking class action status for the case and contends that Apple is guilty of "misrepresenting and concealing material information in the marketing, advertising, sale, and servicing of its iPhone 4 - particularly as it relates to the quality of the mobile phone antenna and reception and related software."

When the iPhone 3GS came out, I preordered it from Best Buy. On the day before the launch, I got a call to schedule my appointment to pick it up. Knowing that activation would be easier the day after the launch, I set my appointment for the day after. I walked in, picked up my phone and was out the door in about 20 minutes.

Cupertino, we have a problem. With over 1.7 million iPhones sold in just three days, Apple's production capacity is at its limits. With so much innovative technology packed into such a small device, there are bound to be some lemons. Many customers have received their iPhone 4 and have no issues, while others have hit the support forums and message boards to voice concerns.

Problems range from inconvenient to completely unfixable. The iPhone 4 comes with one free year of AppleCare, which means that one visit to the Genius Bar can help. With so many iPhones hot off the factory floor, its not guaranteed that even replacement hardware won't have issues of its own. Here's a list of the top 10 iPhone 4 bugs, issues and complaints to watch out for when you receive your shipment from Apple.
