I bought my iPhone 4 open line in Vancouver, Canada last week for use here in my home base in Bangkok, Thailand.  But when I tried using my Thai sim, I get a very weak signal, if not a weak signal, then a no service status.  I also have very weak wifi reception.  What do I do?
I already tried the following:
a. Turned the phone off and then on.
b. Checked all wifi connections – no problem given that all our laptops and desktops can connect seamlessly.
c. I tried restoring the phone to original factory settings via itunes
d. Tried resetting the phone.
e.     Tried different microsims from all networks
f. However, all methods failed given that the network reception is very weak and often reflects – “no service”.  And with regards to the wifi reception It has difficulty in reading even the signal right in front of the wifi router.
I went to two Apple resellers here in Bangkok and requested that they please look at my Iphone and have it serviced.  I was frustrated when they said that given that I bought my phone in Canada, they are not able to support me and should instead try to contact the Apple store in Canada. 
I went to apple.ca website and went to the expresslane support and I was said to register and callback.  Tried calling the 1800 number but given that I was in Thailand I had difficulty getting a connection.

1st sentence, 4th page of the iPhone warranty found here:
Apple may restrict service to the country where Apple or its
Authorized Distributors originally sold the hardware product.
From the Repair terms and conditions found here:
9. Availability of Service.
Apple may restrict service to the country where Apple or its authorized distributors originally sold the
hardware product, and to the countries listed in the table below. A list of authorized distributors is
available online at:

If you do not believe that, then see these search results which confirm my statement.
