So, I tried to update my 3G to iOS4, and basically now iTunes (terrible software) insists that the phone is in recovery mode and must be restored in order to work. It wont restore, and gets an Unknown Error (37) every time, and now my phone wont switch on.
None of those responses helped.
I tried reinstalling iTunes as per the re-installation guide. One time it finished restoring and said "iPhone has been restored, please leave connected blah blah" but then it said that it was still in recovery mode.
I tried turning off my firewall and anti-virus and switching USB ports (don't understand why this would have any effect whatsoever) and that didn't work either.
Have had no phone now for nearly a week, and I'm not impressed at all with Apple's response to what is clearly an issue for a lot of users.
Ok by booting in safe from a thing i found on youtube I have restored the phone, but everything is gone, my contacts, apps, photos, everything.
Anyway, thank you for not helping at all Apple. You can rest assured that I will never in my life buy another one of your products again.
Any chance you're running modified software on your phone? Problems with jailbroken phones can't be discussed here.

I've had EXACTLY the same problem, except I dropped my phone & did a hard reset - that's what killed it (not the new software) - what is this thing you refer to that you found on youtube? I don't care if everything is lost, I just need my phone back! Do you have a link? Just anything that would help me would be awesome.
Hi i had the same error today and I read alot of post saying to uninstall all apple software (itunes, quicktime, ) well I didn't look enough and left out the apple support, unistall EVERYTHING of apple on the computer and try it out. I must have recovered and restored my iphone literally 100 times in the last three days. Any way it worked for me and instead of using my mac that is no longer under warranty i used my dell incase anything went wrong also didn't want to unistall all the backups I had in itunes. good luck.
