I love the internet! Thanks to Randy & Robbie for both sending this in!

R.P has just posted links to one of the latest BlackBerry OS versions on his website

You can find the download links for OS at this link for the BlackBerry 8300, 8310, & 8320.

Don’t forget to delete the vendor.alx file at C:\Program Files\Common Files\Research in Motion\AppLoader\

Thanks R.P.

  1. What happens if I don’t delete vendor.alx before upgrading my 8320? Can anyone inform me what the changes are between and for an 8320? I got x.42 working perfectly, and am afraid of scewing everything up for for just two build numbers higher?

  2. I’d like to know what the changes are as well. I am satisfied with .42 and if its nothing major I’ll just use what I have.

  3. so i can download this and install it to my TMO bb curve 8320?! also, i have a MAC… so how do i install it without a desktop manager?!

  4. Warning: I tried to upgrade my 8320 from to this version ( and Desktop Manager told me there was a fatal error during the upgrade. This did not happen during my upgrade from 4.2.2 to No idea what caused it.

  5. UPDATE: Even though I received the error I mentioned, upon a reboot of my Laptop and of my BlackBerry, I tried again to update to, and worked without a problem.

  6. Does anyone know if this corrects the problem with UMA? I had downloaded a prior version (cant remember which) and it wouldnt allow me to access wifi for uma at home.

  7. Can I upgrade if I’m on T-Mobile’s BB data plan (meaning I have emails pushed to my 8320 as well as internet access). Do I have to wait for T-Mobile to release the 4.5 upgrade?
