If you’re like me and enjoy tinkering and playing with the latest iOS betas simply for the ‘fun of it’, chances are you’re pretty ‘cluey’ about iOS and how the iPad, iPhone and so on work.

As of the iPhone 3GS and iOS 3.x, Apple now signs every single firmware with a signature, unique to every single device and firmware called a ‘SHSH blob’. This means that usually once Apple releases an update, you can’t go back down, you’re forced to go up. Presumably in an attempt to prevent jailbreaking, to enforce security and to make sure everyone has the latest version.

Usually it’s pretty easy to downgrade if you’ve got the SHSH blob for your device for the firmware you’re trying to downgrade to. Unfortunately, as of iOS 4.2.1, Apple is making things somewhat trickier.

So Apple this morning released beta one of iOS 4.3, bringing with it a whole heap of little tweaks and a couple of major features, including the new ‘Personal Hotspot’ feature.

Personal Hotspot extends on the existing tethering support in iOS by adding WiFi as a sharing method in addition to the existing Bluetooth and USB methods.

As far as I can tell, I’d believe it’s tied to the tethering settings; if you carrier has tethering enabled (and depending on your carrier, you’ve paid for access), you should have access to WiFi tethering; it’s just another method in addition to bluetooth and USB tethering. However, don’t quote me on this!

When iTunes Ping originally debuted in September 2010, for the first few hours Ping let you connect your Facebook account with your Ping account, making it easy for you to find your Facebook friends who are also using Ping. Unfortunately, that’s as far as the integration went, there was no ability to share things with your Facebook friends.

Several weeks ago, iTunes Ping introduced Twitter support, allowing you to connect your Twitter account, see who else you’re following is on Ping, but also goes one step further by allowing you to tweet your recent activity on Ping (Liked items, as well as other posts you make).

Thanks to this integration, it’s possible to pull this data back into Facebook, sharing your Ping likes and posts with your Facebook friends. Sure, it’s hacky, and completely messy, but it works, and is better than nothing until Apple and Facebook kiss and make up.

UPDATE: This has been fixed as of Twitter 3.2.

For those of you that have been running the iOS 4.2 beta on your iPad, you may have noticed that some apps appear to be running a little funky, namely Twitter for iPad.

While Twitter is a universal app that supports multitasking, the way that the iPad version has been coded means that in it’s current state, it will never save account details, as the way that an application has closed has changed between 3.x and 4.x thanks to multitasking.

One way to fix this is to ‘disable’ multitasking for Twitter for iPad. While this means you can’t zip in and out quite as fast as you’d be able to while multitasking, at least this means you won’t have to enter your account details everytime the app crashes, you reboot your iPad or it simply runs out of memory while using other apps (this happens a lot more often than you think, thanks to the iPad’s onboard 256mb of RAM – in comparison the iPhone 4 has 512mb RAM). Due to the relaxed restrictions under iOS 4.x, you can now modify ‘some’ files on your iOS device without needing to be jailbroken.

The following steps will require the following:

  • Property List Editor – part of Xcode which is a free download from
  • iPhone Explorer – Available for both Mac OS X and Windows for free
  • If you don’t have a Mac, skip to the end of the post for more information.
