I keep seeing things measured out like:# 100 X 100 Mobile Java Games
# 128 X 128 Mobile Java Games
# 128 X 160 Mobile Java Games
# 176 X 208 Mobile Java Games
# 176 X 220 Mobile Java Games
# 240 X 320 Mobile Java Games
What can my phone use?

what is the difference in the sizes? once I download them to my pc how can I get them on the phone?'
I have a Mini SD card for it.
I think it is 176x220 but I am not sure.
