Well, if i understand you, you are having an iPad device? hum... actually my knowledge is limited to iPhone apps/tweaks. But since both iPhone and iPad are using the same iOS 5.0.1 all can think of if whatspad doesn't display when it really should have an icon on your home screen is that it might not be compatible with this newer version of the iOS. Please read the description of whatspad in cydia and make sure that the dev of that app specify that it can work on iOS 5.0.1
I've use wifi booster on my iPhone in the past, but that was a tweak which did not have any icon anywhere to be found on the device, just a tweak which seat into the system and change some of the system files. Again i'm not sure if we are talking about the same app since you seem to be having an iPad and also, you should make sure that the wifi booster app in cydia is compatible with your iOS 5.0.1
