They're the same only the keymatprint is different which you can replace.

So when you buy a 7210 you can change it into a 6610, you'll have to buy the covers and the keymat and the keymatprint.
Then you've got to different phones!

I will place the pics where you can see the difference

but the function is different isn;t

which one cheaper

and for the function difference can we just flash the ROm ? or 7210 and 6610 has a different ic ?????

The Radio Module is exactly the same, so no difference.

See the difference!
