The third image is the one that I like best - and with an iPhone 3GS it looks classic.
Well, I also learnt a new trick, covering the lens with a card! Thanks for the tip and the chance to view 3GS photography again. :-)
Is that your regular day-to-day phone?
Thanks for the feedback @maxabit! It's not my day-to-day phone, I keep it mostly to use the Hipstamatic app as I don't have a newer iPhone lol!
