Do all iphones run warm while running edge? or is it just mine?

Recently , I ended up losing an iphone to the "no service" cancer (worked fine for 2 weeks after anysim 1.0.2 unlock and then suddenly started showing "no service")

All fixing attempts failed pointing to a hardware breakdown on the communicationsboard (the GSM radio in the iphone) so i eventually sold it off at a huge discount to someone who wanted an ipod touch

Anyway, I went ahead and got a new iphone (OTB 1.1.1) ahich I unlcoked using anysim 1.1
I noticed that the upper part of the phone (near the camera) starts getting warm to the touch while using Edge...
the older phones was also exhibiting the same behavior....

Having said that, I never noticed any such problem on my older Nokias and Sony Ericssons

While using Edge, the GSM radio on the iphone is constantly transmitting (and receiving data) at high power ....
if there is any weak component on the GSM radio, this could possibly cause it to break.....is that what led to the demise of my old iphone?
could this possibly be a problem that may surface on my new phone too?

Just want to find a correlation between the "no service" problem and the heating up of the phone while using edge...
can other heavy Edge users post their experience please...

My comm board goes very warm when i turn on WIFI,

It seems that some iPhones unlocked with AnySim gets warm during wireless usage.

I unlocked mine in somewhat more primitive way, and I still use this method to unlock my mates' iPhones: http://www.hackint0sh.org/forum/showthread.php?t=6078

I wonder how different this manual way is, compared to what AnySim's automation does.

Warming issues never happened to mine and my mates, and that's why I stick with this method.

I don't think that I qualify as a heavy Edge user, but having looked at a lot of baseband logs, I can say that it definitely does put it into a lower power state constantly. From using mine, I notice much more that it gets warm with lots of WiFi usage and when the battery is charging - but I've never noticed it getting warm from just using Edge. I originally used iUnlock and then more recently I am re-virginized and I'm running the AnySIM 1.11 method on 1.0.2 firmware. I haven't noticed any difference in temperature operation on either of the two methods. They act the same.

The iPhone uses an Infineon S-Gold 2 chipset. It's not bleeding edge technology (which is obvious from the lack of 3G support) but it's also definitely not cheap junk.
