I'm not that slow.
The sticky lists the 8330 with a 5.x version. The only version up there for the 8330m is the 4.x version which I currently have on the phone. On the off chance the the 5.x version listed would work on the M, I downloaded it and took a look at it, and it doesn't appear to want to load on the phone as it is the ESN version.
When using google, I can find 5.x versions for the ESN version of the phone but not the MEID version of the phone. I figured with the vast group of people on here, someone may have stumbled across a 5.x version for the M.
