Ok, let's recap:
1. The OP wants to know if there's a pen tip that works with the iPad. He doesn't want to buy a new pen altogether.
2. Firen responds: Doesn't look good, since the Bamboo Stylus is the only one that works with capacitive screens. Seems like you have to buy a new one.
3. You: Hey Firen, you don't understand that guy, he doesn't want to buy a new one!
4. Firen: But since there are no tips that work, your point is moot, he has to buy a new one...
5. You: But he doesn't want to buy a new one! And btw, @OP, you have to buy a new one!
