Having just installed and started to play around with the latest of my iPhone apps purchases, I will say that I am cautiously optimistic about how much enjoyment I’m going to glean from it. This isn’t another of those throwaway iPhone Apps that I’ll get bored with after an hour: this is a fully fledged social networking application designed specifically for the new 3G iPhone that we now know and love.Strangely enough the designers of  iPling have deigned it sensible to not go with the flow and to exclude iPling from the iPhone apps store; perhaps iPling is so good that it doesn’t need the extra marketing clout offered by the might Apple!As I alluded to, my initial impressions of iPling are really good. This is the first of the iPhone apps that I’ve seen to really play on the social networking side of things while tailoring the app to those with 3G phones. You might think that there wouldn’t be a big enough market to make a social networking app worthwhile but with the number of 3G units already sold, this is clearly not the case.The interface is daring and novel and I can confidently say that you’ll stay interested for a long while.
