samsung and nokia shows if the other side is on a call by an alert says Waiting.

hey guys .. after a long journey with Nokia & Blackberry .. finally i got my iphone 4 .. for my previous phones when calling someone and he is in a call i used to know through a waiting alert ! what about the iphone 4 ?! is there any app that i can use to show me that other side is in a call or...

if limest0rm was just a fake jailbreak i wouldnt care, but the guy that did the fake limest0rm video says he is from the dev team and added a donation button in their name!! that is just lame… fake jailbreaks is one thing, scamming people for money is another !!

Limest0rm ! ok .. what is it all about ? Jailbreaking ! i guess waiting for the redsn0w will be better.
