I have downloaded a prerelease of 4.5 and apparently installed it successfully (on my PC, that is). But application loader does not recognize it as available, I'm stumped. Any suggestions?

Its beta, follow the instructions to remove the vendor.xml file as you would for any operating system not released by your carrier.

Thanks. Where might these instructions be found?

Umm, that would be number 4 in the link provided.

Thanks, all. I've now successfully installed ver 4.5.0.10 on my 8320. It's working fairly well, considering it's not the latest build. New fonts are a great improvement. Checked with t-mobile (usa), no info from them on actual release time frame.

Thanks for the info.
