Good Apps for old iPhones?

Just took a big leap forward in technology by hooking up an iPhone 3 my friend gave me

The iOS version 4.2.1 is quite outdated and 90% of the apps I've tried downloading are incompatible

Anybody knowledgeable know of any cool apps that will work on this thing?? Thanks!

It's actually a massive leap forward for me

I have been using an LG google phone which can't even send or receive pictures in texts. The thing may as well be from the Shang Dynasty the way the world is moving

Ahha ok I've quickly realized there probably isn't a single App that this iOS can run

Oh well
