I only had my iphone 4 for 24 hours when it started to randomly freeze on me. I looked up the internet, including these forums and it suggested holding down the home and power buttons for 10 secs. Initially this solved the several times it did it that day. Eventually it froze one evening while viewing a YouTube clip. I left it overnight in its frozen state.

In the morning it was as if nothing was wrong. The iphone was functioning normally. I took some pictures of the snow outside the house and it froze again. Trying a new tactic I tried restoring the phone, which came up with errors 1603 then on a retry, 1604, then 2009, before inexplicably illuminating and going into recovery mode. I then managed to restore the phone and use a backup to put the phone back to how I want it.

Bit later I wanted to add some photos to the iPhone so I added them into Itunes (10.1.1) and synchronised. The screen went dark immediately after plugging it in and has been black screen (as in looks like its powered off) all day.

I have tried holding the power button and home for 10 seconds, then taking finger off the power to put it into DFU mode, but the screen still stays dark.

I have tried holding the home button when I plug it in, but that just seems to screw my drivers up and I get USB device not recognised. I have to reinstall the apple mobile device drivers.

I have tried another computer and another laptop, but no matter what I plug it into, it says the phone is in recovery mode and needs to be restored, yet the iPhone screen is still black, leading me to assume its still in DFU mode.

I have an appointment with the Genius Bar on wednesday, but this is ridiculous, I've never had this much trouble with my other phones before.

How can I get my phone into a stable condition? Or at the very least, somewhat usable?

    Did you try to restore when plugged into a different computer? If so did you get errors again?

    Personally from the sounds of it there could be hardware issues causing the repeated issues. If restoring the iPhone doesn't work then there isn't much that can be done. The genius will probably attempt a restore and set the iPhone up as a new device, so you could try that at home first but that's about it.

    If it's a brand new iPhone I'd get it swapped at the store you bought it from as it seems to be a hardware fault. Especially if it's within 14 days, just threaten to cancel your contract if they don't swap it there and then – in the UK we have that right.

    Shame you have had a bad experience, but sometimes, whether Microsoft/Apple/Motorola or whatever, you will get a dud device
