How to disable time synchronisation under Virtual PC 2007

One of the benefits of the Virtual Machine Additions for Virtual PC is that the time is automatically synchronised with the host machine. In most cases this is desirable, but I ran into a case recently where I needed to test something using an earlier date, and not realising this I wrestled with the time settings of the guest OS to no avail – it just kept resetting to the current time!

The process for disabling this feature (on an image-by-image basis) requires editing the VMC file and is detailed at Ben Armstrong’s blog.

How to increase/decrease the time your iPhone rings before diverting to voicemail

The iPhone supports ringtone of up to 30 seconds, but most networks will divert to voicemail before you gets a chance to hear the full ringtone.

The way around this is to instruct your network to increase the delay before a caller is sent to voicemail:

  1. Via the Phone app, enter *#61# and press Call.
  2. Write down the message that appears after “Forwards to”. This is your voicemail access number.
  3. Now dial **61*xxx*11*y# (where xxx is your voicemail access number and y is the number of seconds before the call should be sent to voicemail – this must be a multiple of 5 seconds) and press Call.

I have tested this tip on an iPhone 3GS on Orange and an iPhone 4 on O2, but it should work on all phones and networks as it’s a standard GSM feature.
