I honestly have no idea what that flaw was. I heard about somthing like that on all android devices fixed in 2.3.5. Or was it just an email security... Anyways. Guys... There is no perfectly safe environment. Best security is if You keep it safe. Not using open wi-fi networks is the most important thing. Or if You use one, don't do anything personal. I actually have the FB accounts of like 20-30 people who use the open wi-fi network in the subway.
