Installed this the other day. So far I have had no complaints from people on the other end of the phone about the reception (And I have got in the habit of asking due to this phone)
I have found that the GPS Still drops out on a regular basis (Using CoPilot 8 Live without additional GPS software)
I have also found that they have tinkered with the touchscreen.
Previously I was finding it virtually impossible to use without a stylus. Basically I noticed that in the note pad application if I tried to draw lots of small circles over the screen the device had a habit of suddenly drawing a line from the top of the screen, The impact of this was when I was typing a text message all of a sudden I would somehow manage to select all the text and then delete it when I pressed the next letter (Very Annoying). Now I find the screen a little less responsive, but this fault appears have been addressed and improved. I put it to the test in the note pad drawing the crcles again and it does still have the fault, but less frequent.
All in All, I think this has improved the phone's biggest faults.
Still, not going to be risking the TG02, TG03 or even TG100!
They have put me off for life!
