If you ever thought that the lockscreen on Windows Phone 7 devices needed some love from our devs, and quite obviously lots of work, you are probably correct. It may be the simple fact that Android has provided smartphone users with very content-rich experiences with the lockscreen and thus we are used to seeing and being able to do more with them. However, when Microsoft created the one for WP7, they simply went with the “metro” or simplistic approach that a lockscreen is just that, a way to prevent your device from accidentally becoming active while in your pocket, with accidental touches, etc. They threw in some basic information such as missed call, e-mail, sms notifications, as well as weather information, and time, but it is as plain as the day is bright. If you jumped from Android to WP7 and miss a more functional screen, then read on.
If you have ever used lockscreen replacements such as Widget Locker, or any of the lockscreens ported from other frameworks such as the lock ring from Sense, then you will certainly like what XDA Forum Member jayjojayson has found for you. It seems that XDA Recognized Developer jaxbot has been hard at work trying to improve the overall feeling of the lockscreen (as well as several other parts of the OS). He release Lock Widgets and much as its name implies, it will allow you to pin several apps that will fill your lockscreen with all the goodness that you are used to seeing the moment you hit the power button. You can see weather, RSS feeds, information about the available RAM, and much more. Moreover, the widgets can be set to update automatically every 30 minutes.
There are a few requirements such as the need for the device to be dev unlocked, interop unlocked, and rooted via WP7 Root Tools 0.9. So, sorry fellow HTC Radar and Titan owners, but no love for us just yet. Please leave some feedback for the dev.
You can pin weather, rss feeds and ram-info on lockscreen. If someone has problems with tranparent lockscreen, uninstall dynamic background and try it again.
