I didn't have the yellowish tint issue, but CAN recreate the reception issues.

Could of data points. I can re-create this with signal strength of between 2-4 bars. With that sort of signal, in about 20-30 seconds I can get the signal to degrade and go OFF. Even showing the rare but equally deadly GPRS DOT. Anyone seen that lately.?

IF I have FIVE bars, full signal, I CANNOT RE-CREATE it. It would appear that the phone is going into some form of searching or channel hopping (ala early nexus one) when the signal is a bit low. IF I have a five bars signal, I can hold the phone in ANY WAY POSSIBLE and do NOT lose any of the signal.

Another data point. IF I have the headphones in, the signal STAYS STRONG even on 3-4 bars. Historically there was some evidence that the headphone cord was used in the antenna, but I don’t think that was ever confirmed.

Of course, touching it with a gloved hand or through cloth, NOTHING HAPPENS.
