I have ATT and if you use SMS or MMS (text and picture) messaging, you will get charged unless you purchase a text package. So be careful when sending pics, etc. Always email! Also, downloading stuff is never free!! Always costs but I get an alert before it downloads saying I have to accept the ATT charge before downloading. The BB messenger is great too! And no, if you pay the $35, you can email, browse, etc unlimited....(taht is with ATT of course.) Good luck. There are a few other Blackberry threads on here too with people sharing theme pages n stuff!! Have fun! I LOVE mine. I have the BB Pearl in Red!
P.S....I am browsing YT and replying to this post right now from my Balckberry!!
