Thanks for the quick replies dowloaded modRana, and skype from ovi store. I do have one more question with my default GPRS, when i try to use conversations i could not able to login either to gmail or yahoo. But with the same connection i can open gmail or yahoo from the browser and do the chat from there. I'm facing the same problem with pidgin. But both seems to work fine with WIFI.

So wats the real problem with the conversations (Pidgin), is it the internet connection speed or any settings needs to be updated.
