Anyone use this? GeekStuff4U | Thanko - Galaxy S2 Telephoto Lens X10 If you have, can you tell us your opinions on this accessory? Also.. anyone else use something similar and can point me in the right direction... would be great too. There's sites like jojophoto and olloclip but they say they are compatible with iphones so I am not sure if they work for Galaxy S2. =) Thanks in advance!
