Google maps is updated to 2.0.0 today with added location finding. (uses cell towers to get close to your location in lieu of GPS hardware)
Jivetalk 1.0.1 preview download now points you towards the 1.0.3 version for OTA download.
And there is a 1.7 development version of MidpSSH that is working quite well. =)
One I'd like to add is the previous version of mapquest navigator that was available for free on the Sprint BBs. I have loaded the 8703e version on my T-mo 8320 and it works perfect, quite a nice product for a free voice prompted navigation. Unfortunately they have removed the OTA link for this software, so I have extracted the 8703e files from my 8320 and hosted them at rapidshare so people could load it through the desktop at least if they'd like to give it a shot.

There's the link for it, if there's demand to get the 7130 version, which works on the 8100 series, I do have it installed on a work 7130 and could extract it from there. But I'd have to see some people ask for it to go retrieve it.
