I AM NOOB! (and sorry for my english)

last week i bought a 9000 bold firmware 4.6.0.303(platform 4.0.0.248)
i have some questions to ask. i`m on vodafone carrier in Romania.
1.i have some problems with my wap browser.there`s no "go to" and i can`t really navigate.and the "battery pull soulution" doesn`t work.
2. nothing that i`ve downloaded and supposed to work on internet doesn`t works.apps like opera, app world, yahoo messenger.
opera gives me the firewall error.
"bb app world is having trouble connecting to the bb app world server.verify your network connections and try again".i mention that i want to use these programs on wap interent.not wi-fi.
3. can`t download facebook app for my bold because it`s supposed to download via app world and that`s not working.
4. i want to download some apps and some games.how?

You need a blackberry data plan from your carrier.
Do you have this?
