A report issued by AdMob (via Om), which serves adverts to mobile websites, notes that the 3 Skypephone is now the number 5 mobile internet device in the UK.

It’s a new entrant in their top twenty ranking of handsets, and made up 2.7% of all ad requests in March 2008 — the top handset’s share was 6.6% by way of comparison.

Of course, this isn’t entirely surprising — 3’s keenly priced unlimited data package (minimum £5 top-up per month on pay as you go) means that the 3 Skypephone is a good deal for those who want to talk and surf on the move.
