Hello, Hopefully a quick question and I apologise in advanced if this has already been asked before but I've already spent 3 hours try to do this now...... I have a Samsung GT- I5700 and want to put the latest version of android on it so that I can run whatsapp (as this needs android version 2.1 or higher). I have downloaded Samsung's New PC studio and used upgrade mobile phone but that didn't work... I also couldn't find any option on the phone to do it either? Any help would be much appreciated. Dan.
