I concur on the JRebeiro Esmertec... I didn't like Esmertec until this version and was using the outdated Taos Midlet Manager. I've now switched back to Esmertec entirely.
I was using Cloudyfa's esmertec and it worked pretty well. This new one (which was actually ripped by no2chem, jrebeiro just cabbed it) works even better.
