Good News for Gmail users who want to communicate with more than 10000 people using Gmail. Gmail increased its contacts limit frmo 10000 contacts to 25,000 contacts. It includes Google Apps users too.
Also, previously an individual contact could be no larger than 32KB — big enough for most people, but not always sufficient for those who like to keep a lot of notes on individual contacts. Now, each contact may be up to 128KB in size, allowing you to store more information in the notes field.[source]
