First of all, thanks for your efforts. AFAIK this is the first real SIP software for BB, so congrats!!
However, as a FOSS lover, user and creator, I can't avoid requesting you to consider releasing your client as Open Source. There are (guess you already knew
) several business models that work well with FOSS.
Anyway, I will try and help improving it reporting bugs.
Question: will it be able to run in background??
Thanks in advance, and congratulations again.
