how can I use gmail and yahoo messenger from mobile?
my os is symbian
You can use Yahoo! Messanger from your mobile phone. Most phones will let you use MSN, Yahoo!, and AIM. Some still have ICQ. If you don't have text messaging enabled, it'll cost you money to use. So be sure. If your phone is anything like mine, you'll go to messaging then IM and just put in your screen name and password.
As for gmail.. I dunno. I guess you'd have to have a web enabled phone. I'm not sure though.
Go to the gmail site. They may say something about it.
I have a web enabled phone..but gmail doesnt load..
