Aftermath
So after getting the iPhone to work as .. a phone, thats just the beginning.
There are heaps of modifications and applications to it. And I will write some about the ones I use and stumble across here.
The easy first: I have set up Wikipedia, Facebook, and Google Reader (RSS Reader) and Beejive (MSN, Gtalk web based client) as webclips. It is easy: Go to theese pages, and then instead of adding them as bookmarks you choose Add to Home Screen. Then you have a shortcut on Home screen to theese places.
Then I have added some other applications that I think is good to have:
Converter Converts between everything you ever imagine. Currency as well!
MobileChat Chat client for MSN, Gtalk et. Is native (in comparison to Beejive). Can force WLAN to be on all the time
Tevee I installed a norwegian modified one for norwegian channels
Flashlight Turns your iPhone to a flashlight. Brightest screen of white!
In addition I have played a little with the instruments (Guitarist, Pianist, Drummer). iPhysics game is quite popular since it makes use of the accelerometer. Terminal is also a good thing to have if you want to access the inner parts of iPhone without installing SSH Deamon witch will make good use of you battery (I have not installed it, but it is possible to turn it off and on with some preference application I have heard)
