I hate to say it, but this is not an absolute problem with the OS. I have .180 and use a Jabra JX10 everyday with ZERO problems. It has much more to do with channel ID or outside interference on your WAP and/or Router perhaps.

I'm on a Linksys WAP without a problem, and it's not a TMO router either. I'm sorry for anyone having trouble, but it isn't really accurate to say the problem lies with the .180 upgrade.
