Also, as I pointed out in the thread, have you tried a battery pull restart? Pull your battery out of your device for about a minute and put it back in. Sometimes it can be as simple as that.
Depending on whether BBM has really been blocked or not will determine how that may affect your contacts, ect. I have heard conflicting reports on BBM being shut off. I would check with you service provider in the UK to get a official answer.
Hi Nadia, yes, your contacts being absent are because of RIM's shutdown of BBM services to the UK. They should appear again when connections are established again.
When you have contacts, chats, ect, all that information is controlled by the RIM server. The server creates a temporary file with connection information for you and your contacts. Then the server determines which contacts are logged on and sends that information to your client, as well as letting the contacts know you're available. After that, the server is no longer involved, and all communication is between your client and that of your message recipient. With BlackBerry Messenger, however, the server stays involved as it would if you were sending e-mails. All communications go through parent-company Research in Motion's servers as you continue to exchange messages. That also means you can't use BlackBerry Messenger unless you have a BlackBerry Internet plan, or data plan.
Best of luck,
