Hi, I am currently waiting for a replacement phone but I also have had a problem with overheating and I have only used the charger that came with the phone plugged into a surge protector type outlet. The first time I got the overheating message was when I originally charged the phone after I had purchased it (6/28/11). Then, although the phone often felt hot to the touch and did not seem to hold a charge very long, (even on standby) and had a host of other problems, I did not see that message again until after a factory reset which was done with direction from tech support.
Following the reset I continued to have problems with the phone turning itself on to airplane mode and my inconsistent ability to turn off airplane mode but some of the other problems seemed to have been resolved. For example, I was able to download the system updates 04 and 05, which I had not been able to do previously. However I am now unable to connect with the 3G network at all and can only access the internet via my home wifi connection. The blue circle with a slash icon appears in the phone's banner all of the time regardless of the settings. I can make calls but cannot send text messages and at times the screen freezes and powering up can be very slow and sometimes gives me a message about "twlauncher" having failed.
I'm hoping that my replacement phone will have had all the updates installed and the bugs corrected but I'm not feeling very optimistic. I think the company could build a lot of good will by allowing the customers to return problem phones to the stores where they were purchased and have available there some tech support people. Even if they were only there on a weekly basis and could schedule appointments, I think people would feel that a real effort was being made to address their complaints.
