Besides the standard coolness of being able to take pictures and text friends and such, so far I have...
- updating his myspace/facebook
- playing hangman (yes, this does exist, I do it when I'm bored)
Any ideas? I've been searching for variations on texting, texts, text messaging + games, tricks, services. All I seem to be getting are various sites that take your number and sell you ringtones. He's not that into music so it wouldn't be the best.
I know there's a service called KGB that's now in the US that lets you get any question you want answered, but as their website tried to download something my computer identified as malware, I got off there pretty quick.
eta: It is not an iPhone, just a standard generic flip phone.
