LG VX-8100

Has anyone else experienced a problem? Am constantly losing connection to headset since update. Have a Scala 500 which worked great. Flashed twice on Thurs, tech screwed up phone on Fri (had to replace phone). Was flashed again on Sat, which took almost 2 hours and was told that's how long it takes when done correctly. This is 3rd tech that told me this. Haven't really had a chance to check it out but picked up a BT250v. Tech said only way to tell if a software problem, is to test 2 different headsets. 😡 😡 😡
