Voice Over
Taken the initial steps into VOIP (voice over internet) and getting mixed results - yes it saves money especially on national calls, but the quality leaves a lot be desired - one advantage with the mob that I have gone with is that they offer a application to run on my mobile phone so I can take the VOIP everywhere that I go (as long as I can get G3 access).
Waiting to see the bill from my mobile operator to see if they try and charge me for the data that I have been using on the VOIP service even though I have a data package.
