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.
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.
Just in time for the iPhone 4 launch day, Apple has released iMovie app for iPhone 4. If you have already got an iPhone 4 lying around, hit the iTunes App Store now to download this app for $4.99 bucks.
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.
Some of you might have noticed the annoying 1604, 1600 error when restoring to iOS 4 custom firmware in iTunes which is built using PwnageTool 4.0 or 4.01. The error in question looks something on the lines of this.
The iPhone version of the popular social networking game on Facebook has finally arrived. FarmVille for iPhone was first announced earlier this month at WWDC 10.
The iPhone Dev Team has just updated PwnageTool to version 4.01, bringing fix for iBooks on iPhone which was problematic on pwned and hacktivated iOS devices running iOS 4. Almost everything else remains the same except for this issue, and so it is recommended that you jailbreak your iPhone again if were having issues with the last release of PwnageTool.
