I've used my E61 for reservist and find it cumbersome for outfield as it couldn't fit into the SBO pocket.
I would suggest getting the E51 no camera as the E61 is end of line product and you can only get it from secondhand market unless you want to get it brand new from Expansys(Expensive).
We have about 6 phones... all E51.. all suffering the same problem :complain:
But nokia being nokia.. they will not acknowledge it as a design flaw (remember the days of the 9500 communicator - damn hinge can snap ...) - they weren't willing to repair it FOC.
