Thanks to another anonymous tipster who has now found OS 4.5.0.51 for the 8830 floating around on the interweb. I know quite a few of you have been waiting for it.
Just as an example of where it can be found:
http://rapidshare.com/files/128381641/8830CDMA_Public_4.5.0_rel74_PL3.2.0.41_A4.5.0.51.exe.html
Let us know if you find any bugs
NOTE: Do not install this software if you do not know what you are doing. It may make your BlackBerry FUBAR.

The Youtube streaming has worked for me on my 8320 since bet 4.5.0.37. I have emulation as blackberry, i have allow java(everything) checked and it works just fine, i noticed in prior versions that my phone would reset while watching videos or trying to exit a video. Seems to be fixed in .52. They just need to fix the BB Messenger issue.
Is anyone else having issues with BB Messenger contacts erasing?

First change ur file options to view hidden files. Then do a search for vendor. I am sire u will find it. Its in the common file under program files I believe. Can’t remember.

So far so good. I was unable to load on my DM 4.5 on Vista. However, i was able to load it on my XP workstation. And I did delete the vendor.xml file. Not sure if it’s s Vista issue.
So far, I’ve noticed on the new revision:
-Better Memory utilization
-Quicker response
-Voice Notes Recorder App
There’s still a bug with Blackberry Messenger, when after removing the battery, it’ll ask you to update your contacts or it’ll erase them.

Deleted the vedor.xml file – everything installed perfectly – Thanks Canson! The two issues that I have run into are: 1) custom folders are now tan floders that cannot be edited back to their customized colors. 2) when viewing the streaming YouTube feed, the press of any key other than what is available by “mouse” control, causes a reboot. After installation, it is neccessary to then add the DocsToGo apps through the Desktop Manager.

Here are some of the things I noticed with 4.5.0.51:
-Very smooth, quick performance, minimal lag
-HTML E-mail (faster)
-Websites now recognize mobile browser and redirect to their mobile site (Some exceptions, including vzwpix.com)
-Fixed the “wakeup from black screen” button problem, (ex. it would select whatever you have highlighted when trying to wakeup the phone with the trackball.)
-Media player via Youtube Mobile is much more responsive and quick.
-Selection in “column” view problem fixed. (.33 made the page jump from hyperlink to hyperlink even when the link was not in view of the screen)
-Wireless Upgrade (Saw it after I first downloaded the OS but not after I resent my service books)
-DocsToGo (Haven’t played with it yet, but it looks very good)
That’s all I have for now. If anyone knows how to get the Wireless Upgrade function back, let me know.

I’m having problems installing VZNavigator. There is no link to download it on the VZStart page and the “Get VZNavigator Now!” Bookmark just takes me back to the VZStart page. I renamed the vendor.xml file so it wouldn’t load it. Could that have been the problem?

I installed 4.5.0.33 Monday, and had a few small issues (browser wouldn’t let me edit textboxes after the first pass, clicking the ball to resuume from sleep launched the highlighted app, Sprint TV stopped working, etc), so I was pretty excited to see 4.5.0.51. Although the previously mentioned issues have all been fixed, I have noticed the following issues (not sure if it’s just my phone, or if these are bugs):
-there is a 2 second delay between vibrate and ring
-unable to upgrade ‘On Demand’ OTA (Handmark app)
-folders are yellow, with no options to customize
-Overall speed seems slower when switching apps

upgradeed to 4.5.0.51 from 4.5.0.33
8830 from Cbeyond
over all faster in everything.
voice quality is a little better
4.5.0.33 almost hurt my ear. 4.2.0.193 had better voice quality with a little bass to it. I hope the improve this in future versions.
Everything works faster. voice recorder actually works now on 4.5.0.33 was there but couldnt record.
youtube and docs to go work perfect.
The only time it seems to lag is when viewing a photo that is 2mb or bigger.

I just noticed that 4.5.0.51 has been SUCKING my available memory down to 0 several times today! Strange! But when it does that and I do a battery pull it goes back up to like 1,000,000 Bytes (or thereabouts).
Noticed significant delays when installing new software (which I’ve only installed 4 things). Like sometimes a minute or more before it completes (not the downloading, but after while it’s “thinking”).
Richard Not Registered
Posted: July 12, 2008 at 11:20 AM EST
Well, it appears I MAY have to downgrade back to 4.2 if this memory thing doesn’t improve soon. Or at least if I can’t figure out why. Maybe it’s something I’m doing, but I doubt it. I have minimal apps installed and/or running, I’m not a complex multi-tasker on by BB, I have it set to delete any emails over 14 days. And when it restarted just now I jump up to 2,416,807 Bytes. Which is plenty enough to operate.
I’m getting desperate enough that I turned on the “Memory Cleaner” option to clear every 5 minutes (only after this all started because I don’t want you to think that IT is the problem).
Suggestions? Anyone with similar findings?

I believe I’ve read that it will be actual OS upgrades. But of course since this version is BETA, then no upgrades yet until it gets officially released.

Sometimes the media player gets strange with bluetooth headphones that have controls. The pause button on the headset pauses the current audio, but seems to start a prior audio session, like perhaps 2 instances of the player are running. You can toggle between the two audio playbacks by pushing the pause button. three finger salute or battery removal fixes it.

has anyone experienced and major battery drain because of a non-stop data connection? I thought originally it was an app that was running (i.e., Viigo) but turns out its must be a blackberry side process as i restored a 4.5.0.51 backup to an 4.2.196 OS version and found the same issue….
