App Failed - had to refresh, now nothing?
 

so i just got my blackberry today... played with it for a couple hours trying to figure it out. i had all my apps on the main screen, i was in something and a message came up saying something like app failed. it had an option to refresh and its the only thing i could click, wouldnt let me go back to the main menu or. so i clicked refresh. now my screen has the date, time and instead of 5 apps at going across the bottom, its five black circles. i cant check anything or do anything except click the green call button and see my past calls. how do i get my apps back and why did this happen???

battery pull
(take out the battery, leave for 30 seconds, put back in, wiat for reboot)

okay sounds simple... but how do i take the case off my blackberry so i can take the battery out?

huh?
There is a battery door release somewhere.

Or do you have some kind of other case enclosing everything?

yea it came with a black case covering the whole thing and i dont know how to take it off and i dont wanna yank it hard and possibly brake it

Perhaps look at the user guide?

i presume therefore its a second hand device?
as a standard new Blackberry doesnt come with any kind of case on it.

my mom got the phone, she bought a case with it that they put on it at the store. i didnt see how and there isnt a user guide for the case.

Is it a rubber gel case or a hard box like case?

its hard, i popped it off, tried the battery thing and it didnt work. i called the tech support people and they said try to take the battery out and put it back in also, still didnt work. any other ideas or do i need to head back to the store?
