Something that's a relatively big deal (symbolically) for me as a new-ish BlackBerry admin.
I just upgraded my BlackBerry 8830 (which had been woefully stuck at OS 4.2 because of lack of support from the phone providers) to BlackBerry OS version 4.5. This is a bit tricker than it sounds, upgrading to an unsupported (by the provider, at least, it is RIM-supported) OS version.
It's not as simple as running the OS installer and letting the BlackBerry Desktop do the upgrade for you. It turns out that you have to:
- Uninstall the earlier BlackBerry Handheld OS from your computer
- Delete the vendor.xml and devices.xml file from the App Loader directory
- Install the new (and correct for your handheld model) BlackBerry OS
- Start the App Loader
- remove the battery from your BlackBerry
- Plug in the BlackBerry using USB
- Click "next" in the App Loader as soon as you see "USB:Unknown" appear in the connection list
- Plug in the battery
- Pick the software to install
- Install (allowing the phone to restart itself several times including waiting for the 507 error to clear)
- Wait 10 minutes or so for the phone to reboot once it's installed
The 4.5 OS is much improved over 4.2, though. If you're willing to take a big risk with your phone (and it's stuck at OS 4.2; it's not nearly as valuable upgrading from 4.3 as 4.5 from what I hear), hit google to get more details on the process.
I also twiddled my procmail recipes on my personal account. A few of them now drop copies of messages into /var/mail/attrembl so the BIS imap client service (crappiest imap client service ever, can't even select folders to watch) can get mail to my phone for me.
