Yesterday I did the whole sync, restore, update to my hacked with a lower case h iPhone and things are working great. I used to have all the NES roms and sketches app and whatever else on there but I never went as far as the SIM unlock route. I have to say that my phone is ALOT quicker than it was before this update, and especially Mail seems to have awakened. I’m not sure if any of the 3rd party stuff truly affected the speed of the iPhone but for some reason, this mega 125MB update did the trick for me.
Now I will patiently wait for the lovely iPhoneDevTeam to re-hack open the phone so I can put a few choice apps back on there.
