You asked, I answer:
Q: yeah, does it have apps?
A: Depends on what you mean. It does have the typical calculator, timer, alarm, etc. and a few games, but as far as I know nothing extraordinary and nothing downloadable.
Q: can you preview ringtones from the phone?
A: If you're wondering whether you can preview them before buying them, the answer, so far as I know (same as c261 I suppose) is no. However there is a nice Multimedia section of the phone where you can blare ringtones to your heart's content.
Q: can you buy ringtones with tracfone minutes? when will it be available for net10?
A1 (mmm, steak sauce): Yes you can...it'll decrement differently depending on how much airtime you've added on your last card, I think. They try to make the price per 'tone $1.99.
A2: No idea. I'll leave that up to the wizards who predict actual dates on things...I don't have the scoop on that.
Hope this helps!
