Sadly, searching the GuinnessWorldRecords website brings up no additional information about this record, as a search on the site for “snowflake” returns 1 result, but for the “rarest gorilla” named Little Snowflake.
If Google posts numbers of the initial downloads, it will be interesting to see if they beat Firefox's effort at Download Day -- guess we'll have to wait and see if "Guinness Book of WorldRecords" changes their listing.
Have you ever seen, searched, or read GuinnessWorldRecords. Have you ever heard of Guinness beer? Typing in any information, like a Web address or a search inquiry, using a phone's cramped keypad is a chore many people aren't willing to put up with.
