First off, VOD gives a semi-annual dividend, not a qtrly one. This dividend is their initial dividend for next Feb of about 51c (hence the $1.02 for the year). Last year it included a special dividend from VZW. This year they are doing a buy back instead with the VZW dividend. This years initial dividend excluding the special dividend is 7% greater than last year. The final dividend which is declared in June is always larger than the initial. Figure the yield as about 6%.
You can find this all on the Vodafone home page including a list of historical dividends and judge for yourself.
