Data stress

I am not sure if 2MB of data is enough to make receiving emails in Africa work... Smart phones have so many options, and really just do their own thing without letting you know what's going on. I do not want Rogers to screw us over with an enormous bill somehow. If we even receive an email with one picture in it, that has the potential to completely use up our monthly allotted 2mb, or at least that is what some sources say. But I thought blackberries had some sort of special data compression that made things actually smaller!?...

Ahhh I need help. I am supposed to be packing and instead i'm screwing up my phone, stressing about data, and getting nothing done by writing this blog post.
