How to get an iphone undisabled?

My iPhone is disabled. I use it as an iPod, not an iPhone and now its disabled. I've tried everything but it won't connect to iTunes so that I can restore it. One time it did let me connect to iTunes to restore it but after 15 minutes of restoring it said that I had to enter the passcode on the iphone to continue but I couldn't bc it was disabled. How do I fix it?

1. Turn off your i-phone
2. When off hold the home button(the only button on the front)
3. While holding the home button connect it
4. This will put it into recovery mode
5. A pop up will ask if you want to restore in i-tunes
6.It will open up i-tunes and restore to a past restore point.
7.It should be like a new phone.
8. After re-sync to get your apps and music back

WARNING you will lose all your contacts this way.
