What happens if you jailbreak it? Does the phone function normally except for stuff that you use outside the "approved" Apple system? IOW, is it business as usual until you need to use it as a wifi spot, for instance? Or are all the functions of the phone altered by jailbreaking it?
all jailbreaking does is allow you to use stuff outside the approved apple system. a lot of it is aesthetic. others, like mywi, have great functionality. All the regular apple stuff works just fine. This is my current home screen, running a Tron theme, with a bunch of blank icons created by iblank, and running 5 icon dock, 5 column, 5 icon switcher, infinifolders (as many items in a folder as you wish)
This is my lockscreen, running lockinfo. gives me weather, calendar, any texts i haven't read yet..
