I've installed Opera Mini v5.1 and Opera Mobile v10 on NOKIA 5230. In both browser when i SELECT any text and COPY then it never works for PASTE function. I tried to PASTE in SMS, or browser address bar, but it never works. 
OPERA MINI v5.1 Problem________!!!

your phone probably doesnt support copy paste..you can only copy paste within respective opera app
