Device support at VerizonWireless.com says that an upgrade from 2.4.330 to 4.5.600 is available for my phone. It gives a PDF fiel of instructions on how to download the update at https://support.vzw.com/pdf/system_update/droid_2_global_instructions.pdf
When I try to download the update the system tells me my phone is up to date on 2.4.330. I called customer support, and they say the download was available but were unable to help in getting it downloaded to my phone. Has anyone else been sucessful in getting this system update?
