Does the N900 support class 4 cards? I bought a 32GB class 4 card, which I got last night. I copied everything over from my existing 16GB, swapped cards, charged the device. Today, I have used it the way I normally do, listening to podcasts on the way to work (~1 hr), then it sitting on my belt. I pulled it out and noticed it was off. Tried to turn it on, and started coming up, then shut off. Plugged it in to the laptop, and it booted up, but the battery was dead. Could the drain have been caused by the new card? Its the only change to my n900 between yesterday and today. thanks, --vr
