Mew is obtained from Emerald. There's an Island Warp Code for it on GameShark. You walk out a building while holding the R and L button, and you appear right on Birth Island in front of Mew, and you battle it.
I got Celebi from Crystal as well, but I have 3 of them (FR/LG/E), and I can clone it on Emerald. Hopefully HGSS will address the issue with Celebi. We have to wait until the game is released and people can extract the data from the ROM.
