Is it really as good as it sounds? I've been with Sprint for about a month (havent gotten the first bill yet) and i haven't bought any songs or ringtones or subscribed to any radio stations. I have the Blackberry Curve and it can do pretty much everything. On it so far, ive gotten ringtones and vids from Myxer, AIM, Yahoo messenger, and Slacker Radio from a blackberry site (its radio stations). None of these add-ons have had charges of any sort to get and download. So my question is, will any of these services have any effect on my bill and cost a tonne more money to have??? Its simply everything, right?
