Hi
When people call me on my Pearl, I can hear them immediately I pick-up the call, but they cannot hear me for upto 15 seconds - meaning they sometimes hang-up.
Is there anything I can do?
Thanks

I had the same problem, did a firmware upgrade and it went away..
Beware my firmware upgrade fried my 1gb Sd card, so i suggest removing it, but you can leave your sim.

Thanks Relic
I must admit - I'm a little scared of firmware upgrades - not sure if I am prepared to have to re-eneter all my settings etc....!

do a back up fist and then do the upgrade, the desk top manager should prompt you before you load. Don't forget to delete the vender cod.
Good luck

PArdon my ignorance but "vendor cod"??!

If you up grading to an OS that is from a different carrier. I'm on Rogers in Canada, but I upgraded to the Singular .71. So I had to delete the Vendor code.
Follow these directions that I copied from another thred for you.

Download and install BlackBerry Device Manager v4.2 (English) from:
https://www.blackberry.com/Downloads...93E4F3BB068C22

This will install the Application Loader as well as all needed drivers. The Application Loader is under:
"C:\Program Files\Common Files\Research In Motion\AppLoader\Loader.exe"

Now you have two choices. Either download and install all the firmware you need, or install the latest firmware you can find for each model you support, and rename the file vendor.xml "C:\Program Files\Common Files\Research In Motion\AppLoader" after each model you install - so after you install Cingular's 8700c firmware, rename vendor.xml to vendor.Cingular.8700c.xml. Once you've installed all the models you need, copy the most recent vendor,provider.model.xml to vendor.xml - it should have the most current definitions for all vendors and models.

"C:\Program Files\Common Files\Research In Motion\Shared\Loader Files"
with names typically similar to the name of the original file. For example, the file "8700M_PBr4.1.0_rel529_PL2.0.0.152_A4.1.0.377_ Cing ular.exe" installs to the subdirectory "8700-v4.1.0.377_P2.0.0.152".

The other option is to just install the latest version firmware you can find and have NO vendor.xml. Application Loader will be able to detect which model is attached and use the appropriate files. This is far simpler.

Now, this should all work fine, but upgrading options are listed on pages 13 and 14 of the Upgrade Guide.
