Apple launched an app today that allows iPhone 4 users to claim their free bumpers. During a press conference last week, Steve Jobs discussed the iPhone 4 antenna issue, and although there was a lot of defensive deflection, as well as some finger pointing, Apple did come through in the end by promising to provide a free bumper to every customer who wants one. The bumper, which normally costs $29, alleviates the attenuation problem which was confirmed by several Consumer Reports tests. Those tests showed that when the iPhone 4 is held a certain way, reception is obstructed, leading to dropped calls and connectivity problems. This led the consumer advocacy group to announce that it could not recommend the phone, which was quite a blow after Consumer Reports called the iPhone the best smartphone on the market just a year ago. During Apple’s press conference, Jobs claimed that such attenuation issues are inherent to all smartphones, and proceeded to demonstrate it with three other popular models from other handset makers. Those companies are none too happy with Apple right now, and claimed that Jobs was engaging is misdirection to turn the debate away from the iPhone’s problems. Jobs also stated that Apple cannot make enough bumpers to accommodate all customers, so the company has partnered with a few other case makers in order to keep customers happy. The new app allows users to choose either the Apple bumper, or a third-party case. For those who think they may be able to snag a free case even though they’re not using the latest version of the phone, Apple is already a couple steps ahead. The app checks the phone’s International Mobile Equipment Identity (IMEI) and serial number to confirm the device is, in fact, an iPhone 4 before allowing the user to proceed with their order. The app is free, and can be downloaded from iTunes. Remember, the free case program is only running until September 30.
