BB Bold 9700 :: Error With Internet And App Downloads?

My contract with orange on my old blackberry (i forgot what it was but it was the blackberry with the ball instead of the square scroll)Anyway when i was told i can have a blackberry 9700 i jumped at the chance and i was told everything will have the same settings etc.I got all my contacts thanks to the helpful orange staff however i can't seem to work my internet and email like i used to.Before i could access the internet no matter where i was as long as there was a signal, but as soon as i'm out of range from my wireless at home, it stops working. This is frustrating because i didn't know how to fix it.Another problem was, when i tried downloading apps, it kept saying that the blackberry 9700 bold do not support them. This means i cannot go on msn.I also need the GPS for tomorrow because i'm heading to London tomorrow and i only had time today to really try to find a solution to this pesky problem.I've had this phone for about 2-3 weeks now.
