My experience is somewhat related to the Red Light of Death issue many of you are facing. I received my AT&T Tilt on 23NOV. I had been charging it with the supplied charger, an OEM charger from my Cingular 8125, as well as two different Motorola AC chargers (with lower ratings, 500 mA?), and two different DC car chargers (one a Motorola the other a Blackberry charger). Of course, the lower rated Motorola chargers charged it more slowly, but I was able to charge it completely with every charger (or so, I thought it was completely charged, but now am not so sure).
However, about 7-10 days ago it began to not charge with anything but its supplied charger or the charger for the 8125. I also began having problems with the battery draining mouch faster under normal usage. I also noted that I would see the wait cursor appear about every 2 seconds when on the Today screen and rarely, but sometimes, when in other screens. SK Tools reported that shell32.exe was consuming 20-100% of the cpu cycles. This all began on or about the same time I did a hard reset without loading the AT&Tcustomizations. But that should not matter and is inconsistent with other user's experiences.
I think I've isolated the wait cursor and battery drain problem to SPB Pocket Plus version 4.0.2 - or more likely, something that I had loaded under SPB Pocket Plus. I haven't bothered to further isloate the SPB Pocket Plus issue as the hard drive on my work laptop crashed.
Still, I find it odd that the phone has suddenly become very picky about its power source. I never had that problem with any of my three 8125s that were charged with the one shipped charger and the same under-rated Motorala chargers and same DC chargers.
It is worth noting that the batery on my 8125 had died after about 3-4 months. The store rep replaced it for free, but advised me to not leave the phone connected to the DC charger when starting the engine as it can expose the phone to power surges that cause premature battery failure. I don;t know if it's true, but I practiced that protocol thereafter and the battery on the 8125 is still going strong after 8 months.
The 8925 is using the stock AT&T ROM with customization via cab files that are not known to cause any problems.
