Steve Jobs just announced at Apple's Special Event that the company will be releasing iOS 4.1 today. As expected, this update will fix bugs, but it will also add new exciting features...
Apple to Release iOS 4.1 Next Week
Proximity Sensor
iPhone Proximity Sensor & Other Features in iOS 4.1 Update?
Earlier this Month the 3rd round of Beta was handed out to developers and the list of fixes doesn't technically include some of the biggest issues people have had with the iPhone's operating system. The proximity sensor or Bluetooth Connectivity don't make the list, but I have beliefs that Apple is working on them secretly to keep the issues asleep.
Neil Hughes from Apple Insider mentions increased performance in both of these important areas and points out a few obscure fixes as well. Steve Jobs said in July that the proximity sensor issue would be dealt with in an update but hasn't said a word about the topic since. Again I say to keep the issue quiet.
