Just wondering if anyone uses any cache cleaning apps on the Thunderbolt and how they've been working out? It was a huge help in keeping my eris running (somewhat) smoothly and not as important with the Thunderbolt but it's nice having a one-click cache cleaner to take care of it occasionally. Anyway, whenever I clean the cache it will either say "Cache already clean" (untrue) or "Cache cleaned. 1kB freed". Then when I check apps that I know had some cache built up (Market, Youtube, or Browser), sometimes it will have cleaned the cache, sometimes not. Any ideas??
