Hi, I am new to N800 and OS2008. I installed pidgin and configure my yahoo messenger account. I send messages and are received ok by my friend, but when they send me a message, it never arrives.
Any idea what can be wrong ?

sounds like the typical way in which Yahoo IM (doesn't) work, most of the time.

Is there no support for Yahoo though the RTCOMM update (integrates with the inbuilt messenger app) http://rtcomm.garage.maemo.org/.

I have working MSN through it, though from that page I can't see any information about what protocols it supports, etc.

I think my point (well, okay... I know my point) was that this sounds much more like a problem with the Yahoo IM service than with the program that's interfacing with it. If you can send messages and they are received, then you are logged in and "functional" on the yahoo network. If return messages aren't making it back to you, then it sounds like yahoo is dropping them somewhere...
