Now that iPhone 4 has been launched in US, and in some European countries, with lots more to follow in July and August. What everyone is obviously waiting for is to jailbreak and unlock the iPhone 4. Since iPhone 4 comes unlocked in almost all countries except for United States, what everyone really wants is a jailbreak, which requires a new exploit as Apple has already patched all the holes in the most recent firmware release, including the one used by Spirit.
According to AppleInsider, Apple is working on a new software update for iPhone 4, iPhone 3GS, 3G and iPod touch to fix the dreading signal loss bug which has been plaguing users since the iPhone 4 launch, earlier this week. Apparently, there was some discussion going on about iOS 4.0.1 update in Apple Technical Support Forums which was later removed for unknown reasons.
If you have an iPhone 3G and you have this feeling that upgrading to iOS 4 has slowed down your device and that you want to go back to iPhone 3.1.3 / 3.1.2. Or if you are one of those iPhone 3GS (new bootrom) or iPod touch 3G / 2G (MC model) user who has upgraded to iOS 4 only to find out that you cant jailbreak it can follow the instructions posted below to downgrade iOS 4.0 to iOS (formerly iPhone 3.1.3 or 3.1.2).
I must have been asked this question a zillion times by now via email, twitter and on facebook on “how to check whether or not I have the new bootrom on my iPhone 3GS?”. Since it is very difficult, if not impossible for me to reply to each and everyone individually, I thought posting about it for everyone is the only option.
Microsoft today inaugurated their fourth Store in Fashion Valley Mall in San Diego, California. This store is situated right next to Apple Store where there were long queues today of people who are hoping to get their hands on the newly launched iPhone 4.
C.K. of SampletheWeb contacted Steve Jobs about the annoying iPhone 4 reception issue which has been plaguing most users who got the device at launch. The official response from Apple was - you are holding it the wrong way.
You must have heard about the buzz going on about the yellow tint / spot on the Retina display of iPhone 4 screen. This could be present anywhere from top left corner of the screen, middle, to lower corners of the screen. This of course is not good, specially because the new Retina display has been hyped like crazy, both by Apple and Press.
There has been lots of talk on the reception issue of the newly released iPhone 4. Early iPhone 4 customers are not too happy with their purchase as the device is said to be dropping signals when you hold it in your hand. While there is still no official word or acknowledgement from Apple on the issue yet, it was earlier being suggested that this was an hardware issue and Apple might have to recall all these devices for a replacement.
Sn0wbreeze 1.6 has been released. This is by the same developer who is behind other popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3, f0recast and BlackBreeze. Just like the PwnageTool for Mac, Sn0wbreeze 1.6 can jailbreak iPhone 3GS (old bootrom, and already pwned on 3.1.2 with anything other than Spirit), iPhone 3G and iPod touch 2G (non MC model).
The official ultrasn0w unlock is now available for iOS 4 which works on all basebands including 05.13.04 and 05.12.01 on iPhone 3GS and iPhone 3G. Since there is no jailbreak available yet for iPhone 3GS with new bootrom, you cant unlock it as even though the baseband is unlockable. This is because unlock relies on jailbreak. So if you have an iPhone 3GS with new bootrom and you rely on an unlock, it is best to avoid iOS 4 (formerly iPhone OS 4) for now.
