Yes, that is exactly what I want. I rooted and upgraded my S2 to a Cyanogen 10 nightly over the weekend (trying to fix the seemingly un-interoperable Android VPN implementation for my setup) and I was appalled to realise that one of the things I was losing was a local calendar and contacts provider - apparently that was something Samsung added, and vanilla Jellybean is cloud-only. I don't WANT my contacts phone numbers in Gmail. I don't even want Gmail, really; it's a fall back and a throwaway don't-trust-you-with-my-real-email account. I run my own mailserver (Exim + Courier IMAP/POP servers). Is there a good server-only contacts & calendering system written in a sane language (I refuse to use PHP, life is too short) I can add? TLS support a must. Anyone fancy writing one plus the Android integration?
