Another tweak I found.
Pagepusher (flips the page up when switching screens pretty cool)
Sliderbar (adds slider on the side for quick scrolling through lists)
Wolfman,
No problem. Glad you enjoy it. I'm from MPLS too lol 
hey guys i was wanting some recommendations for a good SMS theme (wallpaper behind the text of your messages) as well as new keyboard colours (changing the colour of the keys)
I am searching for an app that enables caller-id for outgoing calls. Whenever i dial a contact (saved in contacts), in the dialing screen, displays "contact name" and "calling mobile....". But i want to view the number that i am dialing.
Please help me in finding if any app is available for this or any trick that iOS has.
No SBSettings doesn't drain battery, and winterboard as well. Things you load in winterboard like themes can drain your battery, apps like mywi etc... you've install on your phone and which appear in SBSettings can drain your battery. Never SBSettings or winterboard by their own are capable of draining your battery.
Off topic, but battery is going to drain all the time. Keep a charger, car charger, and whatever means you need. Once jailbroken it's a all day affair. 
