hey iphone buddies!

i need some advice... i recently dropped my iphone 2g and the glass and digitizer have cracked, but the display is fine!
is there anyway i could replace only the glass and digitizer instead of replacing the whole display unit?

a guide on how this could be done would be really helpful!

i found an ebay seller who's got the digitizer and glass as one unit... would there be a problem in fixing that unit to the display itself??? do i need any glue or is it just fixed to together?

thanks loads!

cheers!
