IOS 4.1 fixes proximity sensor issue on iPhone 4

When Apple announced its latest lineup of iPod music players last week, Apple noted that iOS 4.1 would be released within the coming week. Staying true to its word, Apple today released the update which addresses a number of problems afflicting iPhone 4 and iPhone 3G users.

First up, iOS 4.1 fixes the proximity sensor on the iPhone 4. For those unfamiliar with the problem, numerous iPhone 4 users would find themselves muting or ending calls due to the phone's screen turning back on when held up to his or her ear. The proximity sensor issue appears to have been even more widespread that the infamous antenna problem.

A second issue corrected with the iOS 4.1 update for iPhone 4 users includes improved Bluetooth connectivity. Some users were being prematurely disconnected from their Bluetooth headsets due to a conflict with Wi-Fi resources.

Finally, iPhone 3G users will find some relief with speed improvements courtesy of iOS 4.1. AnandTech performed ran benchmarks comparing iOS 4.1 to iOS 4.0.2 and iOS 3.1.3 -- thankfully, the update appears to solve many of the performance-related problems.

IOS 4.1 also brings an number of new features including HDR photo capture (iPhone 4 only), Game Center, HD video uploads via Wi-FI, TV show rentals, AVRCP Bluetooth playback, and Ping support in iTunes.

If you actually read the anandtech article, you'd see that like iOS 4.0, iOS 4.1 is slower than iPhoneOS 3.1.x on almost every benchmark with the iPhone 3G. Failboat.

I agree.

I'd love it if 4.1 allowed TomTom to run on my 3G again, but I'm not holding my breath.

Surely Apple should have left sending out this preemptive obsolescing until most of us were off our 2 year contracts?

I don't think there's ever been a major iOS version update that has been faster than the previous version -- i.e. 1.x to 2.x, 2.x to 3.x, 3.x to 4.x.

The performance improvements mentioned in the article (and addressed by Apple for the iPhone 3G) are related to iOS 4.0.2 vs 4.1 which is indeed a vast improvement.

Even then, it seems to be measuring a clean run vs. a clean run. Any moderately used iOS implementation had inexplicable freezes with iOS4.0+ which were not relfected in the comparisons. If the freezes are fixed in 4.1, then that is the major "performance problem" that has been solved.

Also, where was it ever stated that the Bluetooth issues were caused by a "conflict" with WiFi? When the iPhone 3G first added A2DP with iPhone OS 3.0, the first thing I noticed was that I could not stream YouTube or Pandora Radio over WiFi while listening with A2DP. It worked much better on a 3GS, but even then I noticed that the signal strength would drop. The iPhone 4's problems, however, are entirely different. The BT range problem includes disconnects at close proximity and glitchy audio ("robot voice"). The BT muffling problem happens when you switch to BT after establishing the call and is likely due to improper behavior or the noise canceling mic (it should not be active when BT is used). During a call, the disconnecting/reconnecting issue triggeres the muffling issue, but they are distinct. That said, I have seen absolutely no indication that this is related to WiFi in any way and I seemed to be the ONLY person on the Internet complaining about the WiFi vs. A2DP issues before. I use both constantly on my iPhone 4 without issue. My issues start when I make phone calls and I can't effectively use the handset due to the face sensor or Bluetooth due to the other problems.
