As mentioned by PHP at http://php.net/releases/5_2_16.php, we are encouraged to move to PHP 5.3.x
We will progressively upgrade the PHP version across the server as per plan below:
1. Telin Server (SG Server) : 26 April 2013 - 2300 Singapore Time
2. Jambi Server (US Server) : 3 May 2013 - 2300 Singapore Time
3. Phoenix Server (US Server) : 10 May 2013 - 2300 Singapore Time
It's your obligation to check and revert if your application/website support PHP 5.3 (which in most cases does support 5.3)
You may refer to http://www.php.net/manual/en/migration53.changes.php for changes in PHP 5.3
New feature can be found at : http://www.php.net/manual/en/migration53.new-features.php
