iPhone 5 activated, stuck with new Bluetooth problem

As I mentioned in this post I received my new iPhone 5 a few days ago, but can't use it at all because I haven't receive my new SIM card yet.

Sick of waiting, as a quick workaround, I borrowed colleague's SIM at work today and finally got it activated. Yeah! Issue resolved!

Then tried to pair with my 3GS (running iOS 6.0(10A403)) to share the connection using Bluetooth through Personal Hotspot and it doesn't work!! WTF!!

Searched the net and can see lots of people complaining about Bluetooth problem on discussions.apple.com.....Damn, this is so annoying....

On 2nd thought, I then tried a few different tests:

First, tried to pair my new iPhone 5 to colleague's iPhone 5, both on iOS 6.0 (10A405), but both can't see each other at all. Urh? Why is it like that?

Next, tried to pair my new iPhone 5 to another colleague's iPhone 4s on iOS 5.1.1 (9B206) which was jail-broken.... again, both can't see each other.

Then, tried on my MacBook Pro (OS X 10.7.5), found that I can actually see all 4 devices - old 3GS, my new iPhone 5, colleague's iPhone 5, and the other jail-borken iPhone 4s.

Very strange, does this mean all the iPhones are not suppose to pair/connect with each other, but it's allowed with MacBook Pro??!!

I am confused.

Noticed there's a new iOS 6.0.1 update available, will give that a try on the new iPhone 5 and see if that makes any difference...

Upgraded to iOS 6.0.1 doesn't make any difference.
Now that I got my new SIM, found that with Personal Hotspot enabled on iPhone 5, still can't connect from the 3GS using Bluetooth.

However found that in iPhone 5 Personal Hotspot, there's this "Wi-Fi Password" setting for you to connect using Wi-Fi, and found that works ok. So I am now using this to connect my 3GS to iPhone 5, finally got something that's working...
