Connectivity problems?

I have a Nokia Bluetooth headset BH 216 that I got with my E72. The headset is not getting paired with the phone but it would get connected when I bought the phone initially. Recently, I connected it with an E51 too. I had restored the factory settings on my E72 because the spacebar key was not working. Please help.

I don't think there's any other explanation of the problem except that there's a problem with the piece you've bought. However try doing a hard reset — hold the Capslock + Space + Backspace keys and simultaneously press the power button. Keep these keys pressed till the handset restarts. Check if your handset is able to pair with other handsets and services for transferring data etc.

I got a Samsung SGH-900 from London. I have a YouTube Downloader in my PC and I have downloaded many videos and converted them from MPEG-4 to 3GP so that it can play on my cellphone. When I transfer the videos in the memory card, they can be seen on the computer screen and the mobile phone's memory card. But when I unplug the data cable and check my memory card videos are nowhere.

It's possible that the videos are hidden. Check and see if they are — right click on File, go to Properties >> Hidden. If you've tried placing them in a specific folder, go through the File Manager option and check the memory card for the folder. The files should show up there. Sometimes the handset won't always locate all video files if you're trying to access them from the media player. If yours is a Windows Mobile Omnia device, refresh the library in media player settings.

I plan to buy a touchscreen phone between ₹5,000 and 10,000. I am confused between the LG Cookie Pep, the Corby Speed CDMA and the Nokia 5233. Suggest?

All the three are really good choices. The Corby Speed with CDMA offers connectivity which is much faster than EDGE and almost as good as 3G. But this also means you'll have to switch over to the CDMA carrier forfeiting your existing GSM numbers. I'd go with the 5233 otherwise, as the UI is easier to manage and the Ovi store has quite a few goodies to enhance the phone's capabilities.
