Competition in the streaming music business is heating up. There are more options now for consumers, whether they're seeking free radio stations or customized paid music services. Spotify has just launched a major update to their iOS app, bringing the software to version 0.6.0.

The latest Spotify features a completely new interface with a sidebar that can be accessed by swiping to the right or pressing the menu button. The song you're listening to will be displayed on the Now Playing bar, which also acts as a music control. Switching tracks is as easy as swiping the bar. Touching the cover art will open an extended view with even more controls.

Some Amazon Kindle users may have been surprised when they opened the App Store only to read a warning stating "there is a known issue with this update. If you are an existing Kindle for iOS user, we recommend you do not install the update at this time”. Some of the unlucky readers who installed the update were greeted with a nasty account deregistration bug, which wiped saved settings.

The good news is that Amazon has already made an update available to fix the problems. For those keeping track, Kindle version 3.6.2 is currently available on iTunes and corrects the issues. Anyone waiting until the coast is clear to update or who is experiencing the problems can download and install 3.6.2.

It may be sad news for those who are currently enjoying the iOS 6 jailbreak known as evasi0n. History shows that Apple always comes around with a response to the bugs exploited by the latest jailbreak, and this time is no exception. According to evad3rs team member planetbeing, Apple has already patched at least one of the bugs used by evasi0n in the first developer beta of iOS 6.1.3, making the jailbreak inoperable.

His comments appeared in Forbes, where he explained that not all hope is lost. The evad3rs have a stash of several other exploits they could use to put together a 6.1.3 jailbreak, however everything depends on how many bugs Apple fixes with the new firmware. In the meantime, those who have already jailbroken up to iOS 6.1.2 can continue to use Cydia as long as they don't upgrade.

Add animations to the list of customizable iOS features thanks to the evasi0n jailbreak. Animer is a tweak that provides a variety of different options for everyday events that occur on your iOS device. Accessible from the settings, Animer provides Notification Banners, Alerts, and the Multitasking Switcher with customizable behavior.

For example, when it comes to banners, Animer lets you decide from which direction you want the banner to come from and provides fade and zoom animation options. Everything can be tested right in the settings and the animation speed is also customizable with a slider.

If you're the kind of iPhone owner who likes as much technical information as possible, or you're just looking to improve your cellular signal, there's an app for that. Signal 2 is now available for jailbroken iOS 6 devices from developer planetbeing. The app offers maps of the closest cell towers and those that are actively communicating with your iPhone.

Detailed information is displayed from the cellular baseband, including signal strength, signal quality and the frequencies each cell tower is using to broadcast. Neighboring towers are also detailed, and the mapping can help you figure out where to move if your current signal is weak.
