Just wanted to compile my experience with this OS update specific to this handset and carrier as there may be some issues that are unique to users of the T-Mobile version of the 8320. Hopefully this will help those of you pondering the upgrade and answer any questions before they develop.
Installation is straightforward if you've done an OS upgrade before. if not, please review one of the many guides on this and other forums for assistance.
- removing the previous OS from your device (wiping) is not necessary.
- if you're upgrading from OS 4.5.0.42 or higher, you may leave the media card installed in the device. if not, remove the card, back it up, and format it before reinstalling in the device to prevent a format read error that causes a device restart loop.
after 18 hours of testing, the device has not died, restarted, or dropped a call based on device errors.
-UMA calls connect cleanly and consistently.
-wifi network detection seems to have lost some speed as it now takes just a bit longer for it to detect and connect to my T-Mobile Linksys hotspot router. i will be deleting the wifi profile database to see if this will fix the issue and report back.
-If you use the bundled MSN Messenger app, the update will revert back to the older, packaged version. delete and resintall the newest version from mobile.blackberry.com, then go into Program Files > Common Files > Research In Motion > Shared > Loader > 8320-v4.5.0.81_P2.7.0.78 folder and locate the file "WLM.alx" and rename it to "WLM.OLD". This will prevent future connections to Desktop Manager from reverting to the old version automatically.
-Bluetooth during UMA calling has finally been stabilized. the static present in previous releases has been fixed, and the reliability has been much improved. a 30 minute test call was successful, as well as receiving calls with the headset.
-UMA handoff stability has been improved noticeably when transferring from UMA to cellular and vice versa.
-Wireless Update. you will probably notice this option in Options > Advanced Options. it works, but once your service books are downloaded, this option will go away as T-Mobile does not support the function.
-service books. you may notice before service books are installed the above wireless update option, and you may also lose your Email Setup icon. this will come back once your service books are updated.
for me this was a very worthwhile update. since 4.5.0.55, the UMA + Bluetooth calling had been pretty much dead for me, as every call would die after 30 seconds with that combo. with this release, it has been completely fixed; no static, no dropped calls, no mid-call reboots. if you had issues with UMA calling, bluetooth, or the combination of the two, i highly recommend upgrading to this release.
if you have an 8120, 8320, or 8820 and use UMA calling at all, i highly recommend upgrading to this release as it resolves ALL of the calling issues that UMA users have been having in recent releases.
im DL the new OS right now...
