What can i do on my phone, without internet?

I don't mean games wise...because i don't have any games on my phone.
I have facebook and twitter through my phone, because you can post and such through texts. What other websites can i do, via texting? Anything else i should check out, that i can do from my phone, without using any internet from my phone?

if its an smart phone you can download free texting apps, you can download google voice app so you can call for free. and mess around with it like root it or jailbreak
