Inevitably, as Windows Phone 7 takes off, so will the number of apps available for it. One of the biggest uses of our current mobile devices is to store books and audio books. However, the apps currently available for WP7 are rather limited in what they can do. With this in mind, XDA member dbroome has released an app to bookmark the audio book that you are listening to in case you need to stop. It displays all your mp3 eBooks and will certainly help you keep up with them if you like jumping from book to book (listening to several books at the same time). The app is a rather useful addition for Microsoft’s brand new OS’ arsenal.

Please download it from the Zune marketplace and leave some feedback for the dev if you find any bugs with it.

I was frustrated by the lack of built-in support for mp3-based audiobooks so I wrote this app. It lets you load as many audiobooks as you have memory for. It remembers where you are in each file of each book (and of course, which file you are listening to for each book).

It has standard transport keys plus the ability to enter HH:MM:SS to skip directly to.

You can find more information in the application thread.

Can’t wait for Angry Birds to come out on Windows Phone 7? Here’s your chance to have a similar gaming experience on your new device. XDA member jabberworx told us that Chicks’n'Vixens is ready to download from the market as a free beta. The game falls pretty much in line with what millions are familiar with from Angry Birds: you fire one animal (in this case chickens) into other animals (foxes) and attempt to use each bird’s “special powers” to knock down a tower structure and progress through levels.

Photography, much like any other art form is a prime subject for plagiarism. Pictures can be easily found on the web and used for whatever purpose you may want. Because of this, there are thousands of fantastic pictures floating around the internet with no indication of who took them originally. However, there are methods for identifying your shots and a very popular and widely used one is to place a semi-transparent image with your name or any kind of description that would link it back to you. This is known as a “watermark”. XDA member andre_alberto just came up with a great app to add your very own watermark on any picture that you take using your Windows Phone 7 device. The app will save you time as you will not have to deal with Photoshop, GIMP, Paint, or whatever program you use to add this. This is a great tool to ensure that whatever you post on the internet can be credited back to you in case it does become a hit.
