You can install Netqin mobile security for symbian if you want an utility that will help you clear the cache and others stuffs. And yeah, android has way more apps than symbian, but don't know if the quality is there. But for symbian, there's an app for everything and they are pretty good, fMobi for example is awesome, its a facebook client. Well happy you joined the symbian crew. May I ask which phone you own ? And hey, there are custom firmwares too, if you want to hack, mod, flash your phone.. That's pretty great
