Hey there :D I currently have a great condition Samsung galaxy ace for sale. Hoping to sell it for 90 or swap it with someone for a half decent blackberry with 3G. Would like to get rid of this phone as soon as possible. Nothing wrong with it, works like a dream and ill be sad to see it go but i benefit more from a blackberry lol:( hope to hear from you soon.
