My 8900 has recently been plagued by errors, such as GPS not working for a finite period, lost of dropping of wifi etc... However Orange keep fobbing me off with excuses, if there anything I can say to them that will get them to replace my unit with a new 8900? As it worked a lot better when I first had the unit?
Have you done a battery pull on your device? Take the battery out, wait 20 seconds and then put it back in. You should do this at least once a week to make sure it is running optimally.
