Yeah, I've been posting a bunch over at Playstation.com. A number of folks have had problems since 3.0. Very similar things: bluetooth connectivity, trophy syncing, YLOD and optical drive "failure." There's even a Facebook group for people with the same issues.
The only things mine is exhibiting right now is the trophy issue (who cares?) and the optical drive issues. Seems as though the PS3 struggles to read anything on blu-ray...after a while (which makes no sense). If I turn on the machine, I can load things up...but after a few minutes, it stutters and then hangs. If I eject the disc (takes a while), turn the machine off and then try everything again...same problem. Works for a few minutes, then hangs.
I've tried talking to supervisors when I call, and I'm told they're busy helping other customers. I offer to wait on hold, and they never answer the call. I've emailed Consumers Services a number of times, and they are no help. I've filed a complaint with the BBB, and I'm just waiting to hear back from them.
Despite the admittedly small number of folks who may be effected by this (in the grand scheme), its still frustrating that Sony acts like they've never heard of this before, despite all the posts on their own forum and the class action suit that's been filed for this very problem.
