NSTimer or NSThread in the background of iOs 4

Question

I need to save NSThread or NSTimer when the iPhone application goes into the background. Is it possible? I turned on background modes in info.plist and opened readstream and writestream as follows ... (I use UDP)

CFReadStreamSetProperty (readStream, kCFStreamNetworkServiceType, kCFStreamNetworkServiceTypeVoIP);

CFWriteStreamSetProperty(writeStream, kCFStreamNetworkServiceType, kCFStreamNetworkServiceTypeVoIP);

But when my application goes into background and locked state, NSThread or NSTimer do not call. So, please suggest me how to achieve background thread in iPhone background lock state?
