I want to upgrade my Maemo Mapper from v1.35 to the latest version to take advantage of the ever-increasing excellence of this app (THANKS!! Gnuite)
I am running Scirocco (39.14) and I understand that I'd have to upgade to Gregale

My questions are,

1) How difficult is it to upgrade the operating system?
2) Will I have to re-install all my existing apps?
2b) Is that hard to do?
3) Is Gregale known to be buggy? I've read where some folks had a hard time installing apps after upgrading to Gregale.

Thanks, and sorry for posting this message in two different threads.
