When you start talking lawyers, I would think it is best to leave it to the Cisco engineer and his attourney to decide whether it is worth continuing on this path. Apple do not like critiscm and now you have posted the emails on a public forum it could potentially open a rather large can of worms. Your friend would need to have a good lot of money backing him, along with concrete evidence to take Apple on with this matter.
Every day people report bugs on public mailing lists -- and Apple employees typically request more information, or request that a bug be officially reported. Apple, of course, is no different from any other company in this respect.
It's becoming hard to take this thread seriously
It's a public forum for public opinions.
There's no disclaimer in Apple's emails, are there?
Unless there's small print saying that the information given is only for the intended recipient, etc then there's no issue.
People need to stop being so paranoid.
If the Cisco guy felt he had to get an attorney involved for what should have been a very simple bug report, then that's unfortunate. If he's going to stop the dialog on what could have been a productive conversation between two vendors who inevitably will have to work together to solve any interoperability issues becuase he feels it's a "trap," then I guess Cisco engineers can't be as awesome as we think.
People criticize Apple all the time and don't get sued for it, and never consult an attorney about it.
'Cisco' certs are hardly something to brag about. They give them away like candy.
Even then, that small print is not legally binding. You do not enter into a contract when you email/respond with someone. Scare tactics only.
Dude, take my advice. Ask your friend to stop being so paranoid. Pass on Simon's email to your cisco friend. Let him contact him. This is an open forum and people have the right to raise concerns so no need for an attorney here.
By reading your friends response it sounds like he knows exactly what he's talking about and maybe that's why Simon is so interested in talking to him. Hell, this might even land him a job at apple ..who knows?

Does he really respond to his emails? Damn, he must get a ton a day. I was going to send him an email asking him why iPhones don't support HSDPA+ but then I realized he won't even read it.
Wow really? .. Although i do agree that its possible to have a number of people with paper ccna's, ccnp's etc by cramming questions.. it is not so easy to get the CCIE certification as this involves a very tough 8 hour practical examination and the failure rate is pretty high.
There are only 27000 CCIE's in the world for this reason. Im pretty sure that theres more candy in the world than that.
Im not saying they know everything there is to know about IP and protocol stacks as the OP suggested. But if I identified an issue with the iphone protocol stack and i had evidence of this, then i dont see how there are legal implications about this. Plus, we dont need to assume that just because he has a CCIE that he works for Cisco.
When it comes down to Cisco yes, but when it comes to more general topics they are completely in the dark. This is a big problem with something like CCNA. It pretends to teach people networking but it doesn't. It teaches you how to use and configure Cisco switches and routers. I've seen too many Cisco certified engineers lacking basic networking knowledge. In other words, it's not about having certifications, it's about having actual knowledge. Being a Cisco engineer can look very cool but they don't hire you for your coolness. Nowadays the market gets flooded with Cisco certified people which devaluated the Cisco certification a lot. Where I live being Cisco certified doesn't mean much because of that.
Cisco is also known for a lot of incompatibility problems and other very strange networking problems (their ios is known for this). It's also very likely the Cisco equipment is causing the problems. In the world of wireless networking one needs to remember that wireless signals are very unreliable and very unstable. If something is a bit wonky it can cause a lot of very strange problems or things simply don't work properly for some strange mysterious reason.
I do half agree with you. A cisco certification or a CCIE certification for that matter really does focus a great deal on how things are done the Cisco way. I would not understand why anyone would want to learn about a cisco proprietory protocol like eigrp or similar. But I will say this.. for those who actually follow the proper CCNA curriculum, cisco provide a far better overview of foundation topics than any other vendor certification.
im not sure what sort of incompatibility problems your talking about? ive worked on various multi-vendor solutions and as long as open standards are used, ive never had an issue with Cisco/Juniper/Extreme etc etc. Perhaps your referring to the consumer level products.
Umm.....you may want to do a bit of research on what it takes to get the CCIE certification before you further stick your foot in your mouth. Its not your typical read a book and take a test on a computer scenario. What level of education do you have in the wireless networking field that makes it so easy to knock down and marginalize this guy's experience? My guess would be none or barely better. Please feel free to correct me if I'm wrong.
If the engineer reports it as a bug, Apple cannot sue the guy for knocking out the product. He can then reply to Simon P, with the bug ID, so communication can occur through the ticket.
I would say the a custom written app has been used.
Not just that, some guy from the Core OS dept, got back to him. If they were going to sue, why forward the email?
Can anyone here with an iPhone confirm or deny my Cisco guy's complaint (see original post) with iPhone - complaint being that the iPhone begins to show about 50% packet loss at around 6Mbps throughput under TCP, effectively limiting TCP throughput to 5-6Mbps on the iPhone. UDP shows no such issue.
And I don't know what version of hardware he was testing on but he says it's an issue with the "TCP stack" which would be software.
I'm just curious if anyone else has noticed this. I don't have an iPhone to test. I might get an iPhone 4 in the next few days though.

I agree, to me it seems like the Core OS engineer is just doing a diligent job and following up on a potential bug. Apple has a lot of extremely conscientious, hard working staff, it's how you get a job there and keep it. I think you have to have a extremely cynical or paranoid to think it is some kind of trap.
Probably all those acknowledgments bottlenecking. IIRC once you start seeing packet loss the throughout drops 50% and will continue to drop another 50% if it sees further loss.
Since UDP doesn't have that reliability issue the floodgate open.
I'm afraid I cannot confirm this:

Per speedtest.net's documentation, the test runs completely over TCP Port 80, and I can easily achieve speeds well above 6Mbps over WiFi.
Granted, I'm not using Cisco gear; I'm using Netgear. Maybe the poor interaction is specifically between Apple devices and Cisco routers? But it would start getting a little awkward to assume that Cisco is always right, and both Apple and Netgear are both sloppy in their implementations in such a way that they both happen to work great for each other.
HOWEVER, I can further add that I've run speedtests on Linksys routers that bear the Cisco branding (after Cisco purchased Linksys), and I STILL get similar speeds as the test above. So, I don't know what to tell you.
