I bet the title scared the crap out of some of you. (There are no less than 5 of you reading this journal who want to date me.) But that's okay... who needs men when I have a new Treo 600?
I went to the Sprint store today in Campbell and gave the girl there a good sob story about my poor Treo and its untimely death. My friend (after examining the dead Treo's butt) finally figured out what the real problem was -- I'd shorted the power connector out. Actually, some pieces of the power connector should be inside my car charger, because they were certainly no longer on my Treo. (I can exchange the car charger as well; I'll do that later today.)
Whatever pins I had damaged on the power connector were apparently critical to the operation of the Treo, so it decided to become a paperweight. The girl in the Campbell store was very friendly, and after establishing that I hadn't dropped it and that I'd owned it for less than a year, agreed to exchange it for free. So my friend and I drove up to the Sunnyvale Sprint store (location of the nearest working Treo 600) and I got a free refurbished Treo. My new Treo is sitting happily beside me, blinking its little green light. I haven't tried syncing it back yet, but I will once I get home later today. So a happy ending for all... there's a new man in town for me!
Edit (after reading comments): All 5 guys mentioned above have met me in person at least once.
One more edit: All data has synced up happily to the new Treo and I am now getting to know him better. Seems to be a smooth transition, all in all.
