If you’re a fan of tweaks a little out of the ordinary, then AppMosaic by ctrled may be just the sort of thing you look for. Probably classifiable as an app as opposed to a tweak, it portrays the top 200 apps (free and paid) in one elongated mosaic. It only depicts the icons, but by tapping on them, a box appears at the bottom of the screen denoting the title and its publisher/developer.
Since the App Store app only seems to load 25 entries at a time (the rigmarole of scrolling down and tapping "see more" can get tiresome if you’re interested in the broader scale), AppMosaic is certainly useful because it allows you to view all of the top free and paid apps with very little scrolling.
Having said that, it’s WinterBoard dependent, and I, for one, like to avoid the very outdated, bloated visual modification jailbreak app wherever possible. If you don’t have an issue with WinterBoard, and think the mosaic looks good, or will be helpful in your quest to find new apps – or all of the above – then fire up Cydia and get downloading.
Additionally, it clashes quite heavily with Springtomize 2 (at least, in my experience), and would not install until I completely disabled it, so you may want to take this into consideration before you do download it.
It’s available over at the ModMyi repository – a default entry to your Cydia source list – and is absolutely free of charge. There are no modifiable settings – the icon simply sits on your home screen, so if you no longer wish to use AppMosaic, then simply open Cydia and remove it.
Of course, you will need to jailbreak your device to install this tweak. For jailbreaking the latest iOS 5.1 (tethered), follow the instructions posted here to jailbreak using Redsn0w, or here for Sn0wbreeze. For jailbreaking iPhone 4S and iPad 2, you can simply follow our step by step tutorial posted here to jailbreak iOS 5.0.1 using Absinthe on Windows or Mac. Those of you with an iPhone 4, 3GS, iPad 1, and iPod touches can use Redsn0w or Sn0wbreeze to untether jailbreak on iOS 5.0.1.
