too comfortable on 1.1.1
Everything is nicely setup on my 1.1.1 jailbroken phone - so there will have to be a really convincing new feature to get me to move.
i use books and lighttpd to read long articles, books and pdfs - have an automatic script to copy them with scp from a folder on my desktop.
locateme does a decent job of jump starting google maps with my current location.
i can modify the summerboard to my heart's content.
i use vnc to connect to my laptop to control itunes when i am lounging in the other room.
i have a bunch of other apps that i use occasionally - but i enjoy having the option (advanced calculators, voice notes, dictionaries in spanish and french, the rainbow light for the occasional flashlight). and then there are the games - i'm not a big gamer, but i love having backgammon, othello, go, chess available even if i am on the subway. labyrinth reproduces my favorite game when i was a kid. and i have become a total fan of EvolutionRGB.
oh, and did i mention how much fun it is to be able to draw little sketches . . .
so, it could be a while before i go through the hassle of upgrading. and, so far, the reviews seem quite mixed about the reliability of upgrading to a jailbroken 1.1.3.
