CallBar
Elias Limneos (@limneos) and Joshua Tucker (@sh8kespeare)

CallBar is an great new tweak which brings the slick iOS 5-style notification to incoming calls. Normally incoming calls kick you out of whatever your doing and invade your screen. You can access all the usual functions as usual; answer, decline, or dismiss.
Supporting both phone calls as well as FaceTime, CallBar offers a a function that we are surprised Apple hasn’t added to iOS 5 yet, and with beta 3 being released recently we’re not sure it will get added before the next version of iPhone’s software becomes public.
CallBar is compatible with all versions of iOS and even works with iOS 5! Available on Cydia for $3.99

This app was covered earlier this week by Josh, and has gained a lot of hype ever since it's release. The tweak simply allows you to change the sound of re-springing your device. The name is misleading but nonetheless is still a cool new tweak for those that wish to customize their iDevice even further.

Anicons
Dan Zimmerman (@DanZimm)

Another great new tweak available in Cydia. Josh also covered this one in depth earlier this week, read more here.
The quick rundown: Anicons incorporates important settings toggles directly on your SpringBoard for easy access. When you tap and interact with the toggles, they turn components on/off and make special animations to show you what state the particular toggle is in. For toggles such as 3G or WiFi, the button shows what the signal strength is and changes depending on reception and connectivity.
Find Anicons in Cydia for $1.99.
SpotEnhancer
Andrea Oliva

This tweak comes from the ever popular TweekWeek project, and is a rather unique one, depending on your knowledge of command line input. SpotEnhancer essentially turns your Spotlight page into a command line allowing you to enter things like "get time" and have a popup appear displaying the time. While it's not exactly practical, it is kinda cool.
Andrea Oliva has added some commands on his website which are:
Get date – Displays the current date
Get time – Displays the current time
New message – Opens create text message
New mail – Opens create Email
New call – Launches the dial pad for call
Google – Open Safari to Google.com
Yahoo – opens Safari to Yahoo.com
Bing – Opens Safari to Bing.com
FB – Launches Safari to Facebook.com
Twitter user – Search Twitter for user
