WiFi Connectivity Problems Caused By iPhone OS 3.0

I for one have experienced connectivity problems with my iPhone 3G over WiFi. My signal is never as strong as it used iphone_os_3to be and even in the house I get no connection where I used to get a connection, all this after the 3.0 update.

Hundreds of people have been complaining of these issues of the iDevice not connecting to WiFi, less signal strength or saying you have a WiFi connection when you don’t.

Apple if fully aware of the problem and will be working to fix it. Some people think that the 3.1 update will fix these issues but some people don’t agree with this so we will have to see. If anyone is using 3.1 Beta do you experience any of the WiFi problems?

Some people have came up with many solutions to try and fix this problem, but they don’t work, some people even tried putting there iDevice in the freezer.

iPhone Battery & Heat Problems

Multiple cases of iPhone’s overheating and the battery of the phone quickly depleting have been causing iPhone users Apple iPhone 3G WWDC 2009problems recently. Most believe it’s down to the software, the 3.0 firmware that Apple released a few weeks ago as it only seems now that users are having these problems.

Apple blame the overheating on the hot weather and are blaming people for leaving there iPhone’s in hot places but the battery issues must be in some way connected to the new firmware as I experienced today.

My iPhone 3G which used to run 2.2.1 would run under moderate use each day without getting into the 20% battery area, with heavy usage it would get down quicker and I would have to charge. But today whilst at a friends house I decided to do some live streaming using Qik, however after about 10 minutes I noticed that my iPhone had heated up considerably and the battery had lost maybe 30/40% of it’s charge. Now I know for a fact this isn’t usual as I’ve used Qik before and the phone didn’t have the same problems using 2.2.1.

It seems that there must be something not quite right with the 3.0 firmware which is causing maybe the CPU to be overused, causing the phone to heat up or something in some setting which isn’t coded properly and causing these problems.

I’d be interested to try out the 3.1 Beta to see if it had the same issues, however I’m not currently a developer so can’t try it but if anyone has tried it leave a comment about if you experience the same issues.

The main 3GS ultrasn0w glitch on hacktivated devices is: need to do Settings->General->Reset->Reset Network settings once.

They have said that stability should be drastically improved for unltrasn0w on the 3GS, for some people however it may take up to 75 seconds after reboot.

To get ultrasn0w 0.8 add http://repo666.ultrasn0w.com/ to your sources.

iPhone 3GS Un-Official Jailbreak Released

Geohot has released a iPhone 3GS jailbreak tool named PurpleRa1n, it’s Windows only currently. It’s available now butiPhone 3GS Logo it’s not an official jailbreak, therefore shouldn’t be used without caution. Some people are reporting it to work, others are not however this jailbreak is missing a lot and also things such as WinterBoard won’t function properly due missing critical patches required for WinterBoard, as reported by Saurik.

If you have to jailbreak straight away use this tool however it may cause problems in the future which you might not get if you wait for the official Dev-Team tool’s which are being released just after Apple sends out firmware 3.1.

iPhone SMS Vulnerability Found

At the SyScan conference in Singapore, Charlie Miller described a vulnerability in the iPhone’s SMS system, a flaw that Apple iPhone 3G WWDC 2009could “allow an attacker to remotely install and run unsigned software code with root access to the phone.

It’s unlikely that this will be exploited vastly, but it’s still a very serious risk due to the sheer numbers of iPhones out there. According to the security researched said that the attack “exploits a weakness in the way iPhones handle text messages received via SMS (Short Message Service),” however he has made an agreement with Apple to keep the details out of the press so that Apple have a chance to fix it before someone else figures it out and makes matters more serious.

Miller only gave the following information concering the vulnerability: “The SMS vulnerability allows an attacker to run software code on the phone that is sent by SMS over a mobile operator’s network. The malicious code could include commands to monitor the location of the phone using GPS, turn on the phone’s microphone to eavesdrop on conversations, or make the phone join a distributed denial of service attack or a botnet.”

Miller will be going into more detail of this at the Black Hat USA expo in Las Vegas later on this years, giving Apple a chance to patch it. Apple have planned to get a fix ready for later this month.
