so the latest OS is 4.5.123?
I remember there being a leaked version of BBM 5 for the 8100 before it came out I thought that there would be something similar for the OS!
Im not sure what the latest version is of 4.5 for it. But it is very unlikely the 8100 will receive 5.0, the 8130 MAY receive it but not the other models in the 81XX line.
