Some new nokia phones shows OPERATION FAILED when receiving big files via bluetooth.This happens becoz the phone memory is lower than the file size to be received. I ve developed a trick.Here it is ....First send the file to your phone normally via BT to your mobile.When the phone will show OPERATION FAILED, just exit to standby mood.Now go to your Memory Card and create a folder of any name.Then exit to standby mood.The phone will show that your memory is almost full.EXIT that warning also.Now
