Usually while using the GPRS connection's to access internet through our computer, the speed of the connection ranges from
* 3kbps to 5kbps(In lower end mobile phones)
* 3kbps to 8kbps(In the average models or most of the mobiles)
If you use EDGE enabled phones you can get an average speed 15kbps. I found this while my friend was using "sony ericson k6308".
There is a hidden administrator account in Vista. If you enable it, the security warnings given for most of the operations in vista will not occur. You can delete the files from the C: (C drive). But it may lead to attacks of virus.
Command for activating administrator account is:
net user administrator password
net user administrator activate:yes
On successful activation of the account, you will receive a successful activation message. After that you can log into the administrator account with the password you have given with the command.
