From yesterday my Blackberry (can't remember what kind I have) has been acting oddly from last night I was on Twitter and that really annoying little black box with that round clock hand going round and round took ages to go and then I got "Uncaught exception application net_rim_bb_addressbook_app(1334) is not responding: process terminated" and from then can't open it Facebook is fine though the little box clock did appear but went away again. It does appear in the main menu and when I tried switching the phone off it appeared again very annoying anyone have any ideas.

What exact model NUMBER?
What exact device OS version number?
What version of Twitter?
How much free memory is on the device?

I really don't know it was just there when I got it so I think its a old version of Twitter and there should be alot of memory on it because I have never downloaded apps etc.

Seems ok now just re booted itself and now its fine

Glad you got it sorted out. In the future, it will be very helpful for you to know exactly what device you have and what software versions you are using.

Please update your profile to indicate your BB model number, not the nickname. There are severalCurve models starting with the old 8300 series. All are different with different OS, processors and memory.

For Info,

If you type in MYVER in a message window it will pop up your current blackberry model followed by your OS version. When requesting troubleshooting assistance it is best to provide all the available information so we can ensure that the advice given is relevant to your situation.

By updating your profile information as Dubdub stated, it will give us an instantaneous outline of your device.
