Unable to view the missed calls list or call list... It is not displayed. When I get a missed call and When I open it, it shows no new missed calls... and no number is displayed

local channels are usually below a channel 1000. they are always on same assigned channel. If your cable box or tv has it, it has option to not display channels with no service on them. you can't reassign the channel numbers. they are channels but not being displayed.

You must first check whether this happened after you installed or changed the theme. This might be the cause of not being able to view your calls.

• Increase the log duration option.
  
• Also check whether the theme is blocking you from viewing the call logs.
  

Your Yahoo! Messenger list will open whenever you open Yahoo! Messenger. But if u r not getting that then to do that, double-click either the icon for Yahoo! Messenger or the program file from your list of applications.

Cause:-
Call logging is not enabled for the Message list.
Ensure call logging is enabled from the Phone application Options menu.
1) From the Home screen, open the Phone application.
2) Display the menu and select Options.
3) Select Call Logging.
4) In the Show these call log types in message list field, select the type of call log to be displayed in the messages list.
5) Display the menu and select Save.

I think you should check the date/time setting and make sure that it is correct, then try to delete the call list again.

your phone is in bootloader mode (3 colors) and when you insert the usb cable you will see on your display USB down-left i remember.         http://www.4shared.com/file/92882688/6d8ff7d8/no_nonsense_4.html   here you have a new rom. just click rom updateutility and follow the steps. if your phone has reached Windows Mobile Logo Screen you must Hold Power + voice speed dial 
Reset the device (do not release Power and voice speed dial) 

After a few seconds you are in bootloader state.
