I got another email from someone with a broken VisorPhone.
A connector had come loose in this guy’s phone, so I took a look at it. The connector in question was the phone jack for the headset. This time, however, a pad was in fact ripped off the board when it came apart.
But I was still able to fix it, since this connector had three pins, two of which were able to be soldered down to their corresponding pads. the third pin I was able to solder to an adjacent component for strength. I then glued the whole thing down with a one-part epoxy glue called E6000. It turned out alright:
Handspring’s poor assembly quality control is strange. A cold solder joint like this should have been easy to spot before shipping.
