[edit] Be careful when upgrading your u-boot partition
If the flashing your u-boot partition is interrupted, you can end up with an unbootable device, which can only be recovered with a debug board. If possible, don't do it unless you either have a debug board or live near someone who has one. Always do it with a battery-backed computer (either a notebook or a computer on a UPS), in case the power goes out. And, if you don't have a debug board or live near someone who has one, always flash a well-tested u-boot (don't use daily builds, for instance, unless you know of other people who had success with that particular build), and don't flash a self-compiled u-boot.
[edit] Be careful when playing with your u-boot environment
Wrong commands on the u-boot environment can make u-boot malfunction, with the same consequences as above. If you are lucky, you can still boot and overwrite it with a sane copy from within linux; if you are unlucky, you need a debug board. Always double-check (with printenv) what you have done before doing a saveenv. In particular, always double-check if you didn't mistype a number; see Bricked for an example.
[edit] Never use "nand erase" unless you really mean it
The correct command is "nand erase rootfs" (or whatever the partition you want to erase is).
[edit] Never plug the USB cable without a battery
Unless you want very scary noises and strange smells coming from your phone.
