hi what should i do

my blackberry curve

wont -

received emails
cant send emails
cant get on fb
cant get on net

Mine has been fine all the way through this week. Is there a difference between work blackberries and private blackberries, ie is mine OK because work has a dedicated blackberry server? Does a clever techy person know? I only use my blackberry for email, calendar and phone never internet or the messenger.

I did see something on the news about it causing problems for personal customers rather than business but then again Alan Sugar was also on getting his nicks in a twist about the whole thing which suggests business problems....

(Can you tell I'm not a clever techy person?? )
