What would a used Blackberry Pearl sell for on ebay?

Question

It works perfectly, but has a partial water damage.

Answer 1

A Pearl with a missing battery door latch recently was sold for $66 plus shipping - another one with the same problem for $91.

Perfect used ones, or ones with minor scuffs,  are going for $112 - $153.

A lot depends on how visible the water damage is and how much it detracts from the appearance, but I'd guess you could get $60 for it.

Ensure you include good photos of the damage in the listing and give some background on how it got damaged -- people are more willing to bid if they understand the provenance of the item.

Are you sure it can't be repaired?  http://www.gethightech.com have videos on how to take apart an 8100 and it's possible you could clean up the unit to make it look better.
