Internet Tethering is a process which allows you to use your iPhone as a wireless modem to share its Internet connection with a computer via USB cable or Bluetooth interface. The iOS for iPhone has this functionality (wired-only) built into the operating system but it is only enabled on selected carriers. Fortunately, there is an app called “MyWi” for jailbroken iPhones which can enable wireless tethering on any carrier you like with just a touch of a finger!
I have been using iPhone 4 for the last 5 days now and no matter what I do, I am unable to replicate the iPhone 4 antenna reception problem which everyone keeps talking about. I know the problem is there, because I have seen lots of YouTube videos which shows it all. Also, Apple has acknowledged the issue now and they are going to fix it via software update which is due in the next few weeks.
iH8sn0w – the developer behind popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3 / 4.0, f0recast and BlackBreeze has just written a detailed tutorial on how to jailbreak iPhone 3GS (with new bootrom) on iOS 4. But as I mentioned earlier, there is a little catch to it. 1) it is a tethered jailbreak (whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on) and 2) it will only work for those devices which have their SHSH blobs (ECID SHSH) files for 3.1.2 (NOT 3.1.3) saved on Cydia.
When iOS 4 jailbreak first came out, it was only compatible with iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC models). Things were even more trickier for iPhone 3GS. These 3GS devices were not only required to have old bootrom, but they were also required to have previously been pwned or jailbroken on anything (like blackra1n) other than Spirit.
There is a new video going around in the wild which shows iPhone 3GS (with new bootrom) on iOS 4 jaibroken using an upcoming version of Sn0wbreeze. This video has been confirmed by iH8sn0w - the developer behind popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3 / 4.0, f0recast and BlackBreeze as legit.
Apple today in an open letter has officially acknowledged the iPhone 4 reception problem, which is confirmed as a software issue which will be fixed via software update coming in the next few weeks. The problem as it turned out was related to the “totally wrong” formula which was used to calculate the signal strength.
Sn0wbreeze 1.6.2 has just been released. This new update brings fixes for YouTube, iBooks and iTunes Error 2 which has been problematic for most users after iOS 4 jailbreak. Apart from this, this new version also brings support old bootrom Spirit jailbreak tool users who can now jailbreak their device on iOS 4 with Sn0wbreeze.
The iPhone Dev Team has just updated Redsn0w to version 0.9.5b5-5. Some iPhone users were complaining about MMS and APN issues on their jailbroken iOS 4 devices. Well the good news is that you can now fix this issue with this latest version of Redsn0w. The official change log is as follows.
By now, most of you might have heard rumors about the iOS 4.0.1 firmware update which Apple is preparing to release tomorrow in order to fix the ongoing reception issue on iPhone 4. Even though the issue is most likely related to the hardware, the buzz is that Apple is preparing a software fix in order to avoid (Apple sold 1.5 million iPhone 4s on the first day) what could be the biggest recall in the history of consumer electronics.
Yes you read that right! iPhone 4 has been successfully jailbroken only within a few days of launch! It looks like the “userland” jailbreak vulnerability which was used by Spirit jailbreak tool was not all that properly patched by Apple, and hence @planetbeing (of Android port for iPhone fame) and @chpwn has managed to get root access on the device using code of @comex’s userland jailbreak method. @Planetbeing posted about this news on his Twitter account.
