Hi ive been happily receiving Push mail for the last couple of weeks on my GS2 and today i noticed i havent received any. I hit refresh in the Social Hub mail app and got a message saying "Unable to open connection to server due to security error" Im also then sporradicly seeing "Device has limited permissions" and "Username and password wrong" I havent changed any settings or passwords etc, but i cant send or receive email now. Ive checked on my PC and there is new email in my inbox, im just not getting it on my phone. I did register with Samsung yesterday to check for software updates, which required me to enter my email address, but other than that i havent changed anything. Ive tried re-entering the account info and password but it says connection error when it trys to validate them. Ive also tried to add a new account (using the same acount) but it knows its a dulicate and wont let me... Can anyone help...?
