Let me start off by saying, I have not hacked my phone.
For me, 1.1.1 is way buggier than any other iphone version. Until I updated to 1.1.1 I almost never had a crash, in fact I think that 1.0.2 did not crash for me at all.
This morning on the train, I was listening to music while using safari. The iPod software crashed 3 times on the way to work. After that, the headphone remote stopped working as well.
On at least 2 occasions today, I also encountered another feature of this release is the "screen flicker" basically when attempting to unlock the screen by sliding the "slide to unlock bar" the screen would flash bright and then turn off. Took me 3 attempts to slide the bar to unlock the screen.
It is clear that Apple does not care about extending the iPhone's abilities, but instead care about restricting it. It would seem clear that Jobs was out and out telling a lie when he said that Apple would take a neutral approach to the 3rd party applications.
I must say that on iPhone day (which was about 8 months after making the switch to a Mac) I was an Apple enthusiast (ok, maybe even a fan boy). I even "sold" 6 of my friends on an iPhone. Today after all that has happened since the release of the iPhone (No 3rd party API, price gouging, Ringtone fiasco, Press releases, and now 1.1.1 ), I am more of a reluctant Apple user. OSX is vastly superior to windows, and I will continue to use it. But instead of "The Steve" getting the "I'm not worthy" gesture from me, he gets the finger.
