UPDATE:
Good news everyone. DevTeam recently posted a tweet where they inform us that they will soon release a new version of Redsn0w utility for Windows. It will be an untethered jailbreak for iOS 4.2.1 using the Monte iOS 4.1 technique.
May be soon we will jailbreak our devices with a new tool from George Hotz (better known as Geohot) called Rubyra1n. On March 27, 2010 George Hotz registered two domains limera1n.com and blackra1n.com, another jailbreak tool Hotz released last year. The new rubyra1n, however, doesn’t share the same data with limera1n.com — an app released in October to jailbreak iOS 4.1. Geohot doesn’t comment these rumors anyhow, but we, obviously, wouldn’t be surprised at all to see him coming out with his own iOS 4.2.1 jailbreak for all devices.
The iPhone Dev team has just released the second beta of their untethered RedSn0w jailbreak (the first beta has been released few hours ago and has more bugs).
New jailbreak is called “Jailbreak Monte”, as it uses new “backup method”. The iPhone Dev Team warns that their beta-version is not a general release and you should back up all your media before using it. There are also other limitations and bugs:
MuscleNerd from iPhone DevTeam tweeted that an untethered jailbreak solution for iOS 4.2.1 will be released soon, probably next week.
scotty6kids78: @MuscleNerd are we any closer to the unteathered #jailbreak for the new #ios4.2 on #iphone4 ?
MuscleNerd: @scotty6kids78 it’ll be here by Xmas (not because we’re sitting waiting for Xmas, but because it’s achievable deadline)
This untethered solution will be applicable to all current iOS 4.2.1 devices, including , iPhone 3GS, iPad, Apple TV 2G and iPod touch 4G. We will keep you updated.
This week Google has released a new version of its client app for Android Market, which will work on any smartphone running Android OS 1.6 or higher.
The company aims to facilitate the process of discovering new software and its purchase. That’s why new Android Market will have a Cover Flow-like style of app listings and include new categories like Widgets and Live Wallpapers, as currently the catalog is filled pretty much with these kinds of software. Besides that, app pages will now have more info and links to related content.

Apple has reportedly disabled its jailbreak detection API through iOS 4.2 software update. The API helped third-party mobile device management (MDM) applications to check for unauthorized modifications of system files. Apple’s jailbreak detection API provided MDM applications direct access to iOS system information and was able to ask the operating system directly if it had been jailbroken. Jailbreak exploits typically change a number of operating system files, and exploit one or another low-level OS features to let users directly load their own or third-party applications.
