Question about AT&T Blackberry Curve 8300 Smartphone
This is what you need to do to correct this issue
pls make a backup of all your data and contacts...
You need to reflash the OS on the phone you should take the battery out first then connect it via the usb cable to the laptop/pc you are using then open the blackberry desktop manager,click on the apploader, then install the OS.
pls not that when u click on the apploader the pin should be PIN:UNKNOWN you make need to do this like 4x before the pc sees the pin:unknown but it will work once it see the pin:unknown you can re-insert the battery and continue with reflashing the phone
