Guys... I have been using mini O2 for a month now but lately I became frustrated with it due to its OS stability problem! At one time it self-resetted.. Hard reset I mean... Luckily I backed up all my data a week ago.. but when I restored it, I lost all my latest SMS messages.. Sometimes, messaging application stop responding when you need it the most.. and at times, there are missing contacts and when you try to update with your MS Outlook or restore the original list, the problem persists... Any advice on what to do... before I decide to get rid of the unit and have a bad impression on the product?
