Upgrading your phone.

Has anyone heard about upgrading your phone,like you do it with computers.Like you can add features or improve the sound quality or something...

Unless your into that I don't see phones going in that direction. There will be flash cards, bluetooth, ect but I don't think you will find that full swapping is the direction that they are heading in. Just think of phones as Apples. =)

Never seen that since fitting a vibrate motor into an old nokia 3210
