How did you Set up Bluetooth on the Sony Ericsson K800i ?was it set up properly?Sony Ericsson K800i has Bluetooth technology, which can connect to other Bluetooth devices like handsfree headsets, or let you easily swap files like pictures, ringtones, videos or contacts with other people for free. It works by looking for other Bluetooth devices nearby and then connects to them to wirelessly transfer files. this is the steps to seeting up bluetooth on k800i sony ericsson

• From the Menu screen, select Settings
• Scroll across to the Connectivity tab and select Bluetooth
• Scroll down to Phone Name and press select
• Enter the new name for your K800i
• Once you’ve done this, you can turn Bluetooth on to make you visible to other devices by following these steps
• From the Menu screen, select Settings
• Scroll across to the Connectivity tab and select Bluetooth
• Select Turn On

To connect your Sony Ericsson K800i to a handsfree device, enter the Bluetooth menu screen and select Handsfree, Your phone will then look for a handsfree device to connect to. When it’s found it, select the device and enter the passcode if required

From the Menu screen, select Settings. Scroll across to the Connectivity tab and select Bluetooth. Select Turn On. To connect your Sony Ericsson K800i to a handsfree device, enter the Bluetooth menu screen and select Handsfree. Your phone will then look for a handsfree device to connect to. Press and hold the 'call' (big) button on your bluetooth device. First it will blinks once, keep holding, then it will turn to steady blue. This is the 'pairing' status.

The steady blue light on the device should go off and blinks every couple of seconds. Next time you switch on the bluetooth device it will be automaticaly recognized by the phone.

You can transfer only media files (don't know why). To do it, go to media, prees "menu", select "recieve using bluetooth" and after that send from sony ericsson. 

Take the phone to a mobile service center and have the curcuit board tested to see if the antenna needs to be replaced or service.

CRAZY - try an upgrade of the phone's firmware or take the phone and have it tested but you can try go to the network settings and try to manually set the phone.

hi! its me kibbs! you can easily download by using your mobile also! first you want to activate the mobile office or GPRS in mobile. Then only you can download themes,wallpapers,ringtones etc.... Otherwise you download the software or (themes,images,wallpapers...) from the internet and you sent it through the bluetooth devices,or via infrared or by datacable...... if you want to download from internet goto this site
