Called them and left a message on a Thursday about a month ago. I also emailed the same day using their website form, indicating the specific issues I was having (model, OS, RAM, etc.). The next day I got a return call from their admin saying only that someone would come to my house and it would cost $140 ($150?) for an hour. Told her I had emailed with the specifics, and I asked to speak with a technical person for a few minutes first, to get their view on my issues, whether they could solve it, and if so, how long it might take. She assured me I would be contacted. I received no reply to my email and no call.
Some users have complained of CPU lockup caused by overheating. Apple released a software update in early March 2008 to fix the problem with mixed results: the deactivation of one CPU core was corrected; however, the runaway kernel problem remained for some users. The problem is aggravated by system-intensive tasks such as video playback or video chatting.
To test Apple's live-chat support, I submitted a question about modifying Siri's voice. I received a wait-time estimate of 5 minutes, and after 7 minutes, I was speaking with a rep named Zann. First, Zann walked me through the steps of checking my system version and confirming my device, and then gave me the correct set of steps to find Siri's preferences.
