Windows Live Messenger (aka MSN) addicts sent 133 million messages from their 3 handsets (pictured) in June alone. Now more peeps can join the party as 3 is adding Yahoo! Messenger to the list.So that's now around 16 million users at your messaging disposal and all for free on pay monthly plans or until the end of the year for pay-as-you-go types.Of course, ‘unlimited' always comes with a catch theses days and sure enough 3's placed a 'Fair Usage' cap on the fun. So all you'll be able to send is... ooh - 10,000 messages a month. Not so stingy after all.EssentialsContact: ThreeRelated stories:Yahoo! invades UK mobiles this weekYahoo goes mobile – take twoHotmail goes mobile on 3
