Wow....U buying the mini O2....well, my fren is a ex-technician from the O2 service centre....as what i'm heard from him, O2 mini is still not stable where it's hardware is still have many problem...expecially the reciever and the antenna, where most customer will found the new set bought unable to hear the other party during calls and also have a very poor receiption....and one generation of stock takes alot of power and u'll find it not lasting with it's battery....and lastly, if uy wan to buy O2 mini it's better that u dun install any 3rd party software in it....guess what?? PDA exxxxx does not test the 3rd party software previously and dun know the compatiblity for the hardware....that what make the system corrupt in few month time...as a result u'll need to do the hard reset...in more serious case u'll need to change the hardware where the service centre might won't do the warranty for that.....that's what i can say bout o2 mini....so be carefull........
