Besides battery issues, the iOS 5 update is now causing some Wi-Fi related problems.
Users have reported having problems with their WiFi connectivity, saying the device is either unable to connect to WiFi networks, or if connected to maintain these connections.
While it is still unconfirmed by Apple, the issue has affected a number of devices, including the iPhone 4S, 4 and 3GS, along with the iPad and the iPod Touch.
One user uninstalled iOS 5 and returned to version 4.3, which temporarily solved his problem. However, after re-upgrading to iOS 5 the problem resurfaced.
In the meantime, you can feast your eyes on an iPhone 5 concept video, detailing the rumored features of Apple’s highly-anticipated device.
The exploits found by the Chronic Dev team that could have helped find an untethered jailbreak were found and killed by Apple, reports say.
Dev team member Joshua Hill announced in a blog post that some of those five exploits the team found in iOS 5 have been patched by Apple.
He wrote: “First & foremost: during my JailbreakCon talk in September, I was excited to announce that the Chronic Dev team had already discovered 5 different exploits for use in our upcoming jailbreak. Unfortunately, that announcement was a bit premature, because in the subsequent weeks, Apple found & patched a (critical) few of those exploits, between the beta versions we used for testing and the final release of iOS5 on October 12.”
However, Hill also included a request in his post: he asked for iPhone users’ crash reports from their iPhones to find new and un-patched exploits.
“Instead of allowing this vicious cycle to continue, we decided to write a new program to turn Apple’s own beast against its master, per se. All this program requires from you is to attach your iOS device to your computer and click a single button!” the member explained in the post.
“At this point, the program copies all the crash reports off your device (which, under normal circumstances, would be sent right back to Apple), and instead sends this data to a secure, private server hosted by your friendly Chronic Dev Team. Next, our program needs to neuter your copy of iTunes, simply by changing your settings to prevent your computer from sending any further information from your device to Apple.”
In addition, the iPhone Dev-Team made an announcement through @MuscleNerd’s Twitter account, regarding the status of a carrier unlock for the iPhone 4S.
“Crazy Thanksgiving weekend! Very promising 4S unlock (http://twitpic.com/7kku4t) is in the works (Not i4, just 4S..that’s crazy part),” the tweet read.
The post was accompanied by a picture linked in the Twitter update.
Apple released yesterday the beta version of iOS 5.1, the first major update since the release of iOS 5 in October.
Soon after its release, developers have found intriguing codenames suggesting that much-awaited Apple products will soon appear.
Thus, the iOS 5.1 code contains references to the iPhone 5 and 2 iPads, internally named iPhone 5,1, iPad 2,4 and iPad 3,3, respectively.
Given that the iPhone 4S was previously listed internally as iPhone 4,1, this reference to iPhone 5,1 could cite the next-generation iPhone model.
The code also lists a new device called J33, which many believe is the future Apple TV box that connects the TV set to the Internet.
The data doesn’t give precise details regarding new devices, but it can help form an idea of Apple’s future release schedule.
Apple recently acknowledged that some users encountered problems with their iPhone 4S battery life and an update to iOS should solve the problem.
The Cupertino company released the first beta of iOS 5.1 for developers on Monday, which many expected to include a fix for the battery problem.
However, according to preliminary analysis of this new version, while some users acknowledge an improvement to the battery life, others reported no change, with some even claiming the problem was now worse.
The site ArsTechica spoke with two analysts to try to understand the cause of the battery drain problem and the reason could be due to the complexity of smartphones.
ABI Research’s Michael Morgan told the site that software is more likely to cause the issue than hardware.
“iOS 5 may simply be using more data transmission or running more background processes to support its new features,” Morgan told Ars. “There is also some potential impact of iCloud services.”
Battery-related issues, or any “undefined glitch,” are a “massive problem” for Apple, Morgan said, noting that it can sometimes be hard to get a solution to the problem with complex software such as iOS 5.
“We tore down the 4S and tested some of the major components, including the new A5 processor,” he added. “Nothing that we tested was significantly different from the iPhone 4, and power draw was right where we expected it to be.”
Given that the current iOS 5.1 is still in beta, this may mean that Apple could still be working on some issues in the software and that the battery problems might get a solution in an upcoming beta or in the final version.
A report from security firm McAfee states that Apple’s iOS offers more security than Google’s Android.
According to the report, Apple’s advantage comes from the fact that the company restricts the way apps can be downloaded from its App Store.
Currently, there have been no known cases of iPhones affected by malware, except those that have been jailbroken.
iOS users can download apps through App Store or through Mobile Device Management, which are tightly controlled by Apple, hence ensuring a safer environment.
On the other hand, the report says, Android welcomes third party management tools on the Marketplace, thus making devices more vulnerable to malware.
iOS currently excludes third-party management tools on iPhone devices, offering its own toolset. By contrast, Android welcomes security apps but by doing so, it puts security at risk.
In addition, given that Android holds the market leadership right now, it is more prone to getting malware because it is the frontrunner.
As a consequence, due to its leading position, Android has attracted new mobile malware attacks, 63 percent in the second quarter of 2011 precisely, despite managing to get ahead of Symbian on the smartphone market.
“Apple’s approach is proactive and focused on prevention,” the report noted. “Google’s plan is apparently to encourage the creation of apps and deal with the problems as they occur, in a reactive fashion. Google’s may be a sensible move to generate a large volume and wide variety of apps, but from the security perspective it creates exactly the kind of environment in which malware gangs feel comfortable.”
