I had a JVM error about 2 weeks ago, went through the whole JL_Cmdr process and installed the new OS. Ever since then, I can receive e-mail, but not send.

I've just kind of been muddling through the problem until I realized today that I haven't received a call for 3 days. I checked my voicemail and sure enough, I still have friends. All morning I've been calling myself, but my BB doesn't ring, doesn't register that I have voicemail and doesn't register any missed calls in the call log.

Any ideas?

You may want to go through the OS reload process again. You shouldn't need to wipe the device, just reload the OS.
