Mexico prepaid Blackberry service (Telcel Amigo)
 

Apparently Telcel launched a prepaid Blackberry service. I noticed in my Amigo online account an option to activate 'Amigo Blackberry'. The prices are as follows based on location (first price shows a 10% tax while the second shows a 15% tax).

7 days - MXN143/MXN149
15 days - MXN238/MXN249
30 days - MXN429/MXN449

No other details are available, but I managed to find a short description of the service:

Amigo BlackBerry Internet: Es una solución que te permite enviar y recibir correos electrónicos desde tu BlackBerry. Además ofrece servicios de Mensajería Instantánea y navegación en Internet

Amigo BlackBerry Internet: It is a solution that allows you to send and to receive electronic mails from your Blackberry. In addition it offers services of Instantaneous Mail and navigation in Internet (worldlingo.com translation)
