Good news for all the power users of gmail specially for those who even store their phone contacts on their gmail account like me, now gmail team has increased the limit for all gmail users which allows you to store maximum 25000 contacts under your google gmail account. Gmail did this because they found many people wanted to store more than 10,000 contacts under gmail account. Sp they have increased the limit for all Gmail users, including all those of you who use Google Apps, to 25,000 contacts.
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.
