Anyone else have experience doing this? My monthly bill for an iPhone with AT&T is $76.40 which includes 300MB of data, 1000 messages, and a whopping 450 minutes (I do have ~2700 rollover minutes though).
I don't feel strongly about Android vs iPhone, but $550/yr is nothing to laugh at.
Edit: For comparison,
