I’ve been thinking, the one thing I do most when I’m on the computer is MSN. Wouldn’t it be great to be able to instant msg on the iPhone? Is that already invented? o___o;?! However one problem is that maybe it’s abit too similar to the sms system, except for the fact that its real-time. Also, you might as well call the friend? But then instant messaging with multiple people at the same time, or altogether in one conversation is an advantage… hmm I’ll need more thought about this one.
Second one is, well recently I’ve got attached to a online multiplayer tetris game where you bomb each other. I’ve been thinking that this application could be designed for the iPhone. I need more thought to improve on this idea.
