Steps for free upgrade PS CS3 to PS CS4

<p>If you've recently purchased a copy of Photoshop CS3 you can get a free upgrade to CS4. I phoned Adobe

customer service here in the UK to ask about it and was instructed to supply:</p>

<ul>

<li>the email address I used to register my copy of PS CS3</li>

<li>my customer number (if known)</li>

<li>the serial number of my copy of PS CS3</li>

<li>a copy of the purchase invoice for PS CS3</li>

</ul>

<p>Email these to <a href="mailto:english-custserv@adobe.com">english-custserv@adobe.com</a> - I was advised

to follow-up the email with a phone call to Adobe

customer service on 020 7365 0733 which you may wish to do if you don't know your customer number.</p>
