Morrison just let me know that he scored a link to OS 4.5.0.101 for the 8830 online. I cannot confirm it since I do not have an 8830 but 8830 users have been left out in the cold with recent OS updates so I thought it was worth mentioning.
8830 OS 4.5.0.101: www.megaupload.com/?d=V1G8IYSR
Let us know what you find in the new OS version in the comments below. Thanks again Morrison and keep the tips coming!
NOTE: Do not install this software if you do not know what you are doing. It may make your BlackBerry FUBAR or just plain angry.

I downloaded and installed on top of OS v4.5.0.77 last night. So far there have been no issues, and I wound up with an additonal 2.5 MB in free device memory — appears to be a definite improvement so far!

Installed today over top of 4.2.2.196. So far much better than any 4.5 I’ve tried.
Two problems:
1. Can’t find my media player app though it comes up when I launch a clip from YouTube or browse ring tones.
2. Can’t find SheetsToGo.
Before installing any apps I have 14M free! More than any OS I’ve tried on this 8830!

Re SheetsToGo
It’s not included in the OS. It’s available for free by registering DocsToGo with Dataviz, and then clicking the update software link. I did it a few days ago, all free and quick.

v.4.5.0.77 installes on Sprint 8830. Only issue after resolving the "no ring tones" issue is the videos. Some play while others don't. I get that message mdeia being played is unsuported format.

Still suffering two issues with this build on my 8830 Verizon:
1. Still no Media Player icon
2. Every time I reboot the phone, when I go into BB Messenger it tells me I have upgraded to a new device and asks if I want to notify all my contacts of a PIN update. My PIN didn't change and neither did theirs!

Installation went smoothly, on my 8830 Verizon:
I heard this OS would unlock the GPS, but I guess that is not true.

It IS true Alfonso. Hundreds of 8830 reports of GPS now working with ANY 4.5 (not just .101). You probably have to turn it on in GPS Options (default is 911 only) and may need to do a battery pull. It only works with Blackberry Maps though, no other free apps can use GPS yet (LBS is all controlled by Verizon’s servers).

DavidB,
Thank you, much for this info. You are correct. GPS is truly enabled and working with Blackberry Maps
