My N900 finally died as a phone (it has the dry joint somewhere under the Sim problem, and staggered on for 9 months or so with me packing the Sim more and more). I wanted to keep on using it, just not as a phone (except maybe for Skype). But I've found that without a Sim in it flattens the battery too quickly to be useful - I guess it must be using all its power just looking for a connection. If you've retired yours as a phone, have you had the same problem, and have you found a cure?
