Apple Releases iOS 4.0.1 To Fix Signal Reception Issue On iPhone 4
The iPhone 4 reception issue has become a major one for Apple, with users complaining about it everywhere and even asking for a recall of devices. In an attempt to fix this reception problem, Apple has released an update to the iOS firmware for iPhone 4, iPhone 3GS, and iPhone 3G.
According to Apple website,
iOS 4.0.1 improves the formula to determine how many bars of signal strength to display on iPhone 4, iPhone 3GS, and iPhone 3G. The real signal strength remains the same, but the bars on iPhone will indicate it more precisely

iOS 4 which was the first version to be released is supported on iPhone 4, iPhone 3GS, and iPhone 3G. In case of iPhone 3G, multitasking and wallpapers are not supported. However you can enable multitasking and wallpaper on your iPhone while jailbreaking it. If you have already jailbroken your iPhone, then you can create iPhone theme on your Computer and apply it using WinterBoard Cydia app.

this is bullsh** it did not work
Fantastic, it tells you that you can downgrade if you accidentally update, but that assumes you have been saving your Blob file all along. Well, if I was already saving my old blobs, I’d probably already know how to downgrade. Oh yeah, you are a superstar, next thing you know you’ll tell me how to become a millionaire: First, get a million dollars….. brilliant.
i hope it works. my first time
Everytime i download one of these files, no matter what website its from. I cannot find the .ispw file! its non-existant! can somebody please help me find it!
I am sick and tired bout this bulls**t iphone/i-tune no ending problem. Why do we consumers have to go thru all this head cracking problem with iphone. It suppossed to be user friendly but the problem keep on surfacing everyday. Why make life difficult adding unnecessary stress as if we dont have enough.
So to hell with all my 4 iphones I’m changing to Samsung.
Good luck to all future Iphone owners.
