I wanted to format my device due to some mailbox problems. Before I formatted, I removed the memory card, and the device felt a lot more responsive. Does anyone else find there device to be more responsive without the memory card. I think I'll leave it out altogether, as I have no intention of installing hundreds of apps, or using the device as an MP3 player.
BTW...after the format, my LED now flashes for the correct amount of time that I set it to instead of lasting less than a few minutes. I wonder if IMAP works any better after the format.
