The offer is available only on select number of phones and only for Portuguese residents, but using fake credentials and a fake IMEI number anybody can grab the extra 2GB. Here is how.

Go to https://www.samsung.com.br/dropbox/Default.aspx. The page is in Portuguese. Click the “avançar” button. Click the “avançar” button again. Enter a (bogus) e-mail address. This won’t be verified and does NOT have to be the same as your Dropbox e-mail address. Click the “avançar” button. Click the “avançar” button to confirm the e-mail address you entered. Fill in the form with (bogus) information. Nome is name.

Senha is the password. At least eight characters, numbers and letters, no sequences.

For CPF, go to this website: http://www.gerardocumentos.com.br/

Click the "Gerar" button, copy the number generated in the box below, and if it displays "Verdadeiro", you’re good.

Dt de Nascimento is a day of birth. Day, month, year format.

Telefone and Celular are phone numbers. In the first box use area code 34. Entere eight random digits for the phone numbers. A different one for both boxes.

Check the box next to "Concordo com as Condições Gerais".

Click the “avançar” button. If it will display any errors in the form, use Google Translate to figure out the errors. http://translate.google.com/ On the next page, select "GT-S5570B" from the drop-down box. For the IMEI in the box next to it, go to this page: http://dl.dropbox.com/u/3471788/imei.html

Leave the base number alone, and enter a five digit number in the serial number box.

Click generate.

Paste the resulting number in the IMEI box on the Samsung page and click "adicionar produto" to attempt to add the number.

It will add the device, IMEI, and a red minus sign in the area below the entry form if the number was accepted.

If the IMEI was not accepted and the device was not added, go back to the IMEI generator page and increase the serial number by one. Repeat submission until it is accepted.
