I just got a prepaid account (Starter 10) and Blackberry Social 15. Why? Just for fun, love my old Bold 9900. Anyway, it is working well. As advertised BBM, Facebook and Twitter are working. However, while I was able to set up an account and associate my gmail at telus.blackberry.com, when I later went to send an email my device said my data plan doesn't include email.
So all this to ask, does the Social 25 add-on give me email? It is hard to tell from the description on Telus' website.
