Hello, I'am also in the East of Chiang (about Doi Saket). I use CAT CDMA as I have yet no other choice.
My antenna is directed to the Doi Saket Hospital CAT Antenna. I use Internet in connection with France servers.
The connection is always very slow since many months now.
But better in morning and day time than in the evening when I have almost all time non more than 10 to 15 KB/s and sometimes below 5 KB/s (so less than 40 kbps, less than an old time modem).
But I don't know what to do (I have some of the best equipments at home). I just pray 3BBB will pass one day on the main road, between Doi Saket and Bo Sang, and that their connexion point will not be too far.

Apple doesn't sell the iPhone 4 in Thailand yet (even if you can buy one at some places).
If the iPhone is unlocked (test before buying) you can use any SIM, but if you have no data plan of any sort from your operator, the iPhone will be just like a dumb phone. No Internet at all, only on Wifi spots (if you can get some for free).
