I am not able to text to these things on my phone for some reason. I think you have to pay extra for it. Also, when texting to get "free" things especially ringtones and such, it isn't really free. You have to pay your cell phone company lots of money to do this. Sometimes it is up to $5 depending on the company.
Plus, you will get lots of spam text messages sent to your phone. Telemarketing on the house phone, spam messages in the email box, junk mail in the snail mail is one thing...but I can't stand to get those things on my cell phone!! I haven't gotten any yet, but I do get lots of wrong numbers and those drive me up the wall!
