4.5 upgrade from t-mobile - IMPORTANT!
I just did this last night. I had the 4.3 Desktop Manager and tried to load the 4.5 O/S. Three hours later with multiple retries and panic I'll share some advice. Use the latest desktop software available when upgrading (4.6).
It turned out the 4.3 desktop software didn't have the drivers needed, so half way through the install I would get a communication error and my BB was a brick with a blinking red light. After that, my USB connection would constantly connect /disconnect.
I have it up and running now, I think by luck more than anything. Just thought I'd share a useful bit of info.
That's strange. Been using 4.3 DM with all my OS 4.5 upgrades (I have used many) including .81 and .93 as of late....

Where were you able to download the 4.5 OS? I went to the Tmobile store today and was told that they officially released it 2 days ago but when I got home I don't see the download link anyway on their site.
I Used 4.2 and it ran fine.
DrSuha, try going to t-mobile.com/bbupgrade. Find your Blackberry and type in your cell phone number.

Well now use the apploader and the software will recognize your phone. Then do the upgrade or reload and you will be good to go. Doesn't mean you are bricked. Trust me. Bricked means no response at all from apploader or anything at all. I'm a brick expert. Lol.
the link for 4.6 dm is h t t p : / / w w w . vodafone.de/hilfe-support/blackberry/112014_132840.html#rights
i wiped my blackberry 8120 pearl with jl_cmder, and now i've got no OS whatsoever on the device.
i've installed the 4.5 OS for the device onto my laptop, but AppLoader doesn't know where it is, or can't recognize it.
to top it off, my Desktop Manager doesn't recognize my blackberry anymore.
fixed it. vista was giving me problems, not blackberry.
i'm a beginner with all this blackberry stuff, but for those whose devices aren't being recognized, try the whole setup with a different computer.
xp worked for me when vista was about to bring on a migrane.
