I got my Ace from Hong Kong and I'm using it in Canada. Above the signal bars on the left side, there's always the letter "R". I'm not sure if it stands for roaming or reception? I have 'Use packet data' and 'Data roaming' unchecked, and 'Use only 2G networks' checked under 'Mobile network settings'. Just so you know everyone know I'm with Fido and I only have a voice plan. Any help would be appreciated!
