Sprint iPhone 4 won't restore?

I have a Sprint iPhone 4 that I forgot the passcode to and it now says CONNECT TO ITUNES, and won't let me do anything else. When I put it in DFU mode and attempt the restore, everything goes right until the end it gives me an error. The restore has to also update my iPhone from 6.1.2 to 7.04 if this information helps any. Also I noticed that there's a new version of iTunes that I need to download. Could that be the problem?

Yes, you should update your iTunes to the latest version before restore. And if you preform improperly during the restore, iPhone might can't connect with iTunes. If your have problem, for example, iPhone can't connect to iTunes, iPhone won't turn on, iPhone stuck in Apple logo, etc. When update or restore, use Tenorshare ReiBoot to fix this! It is free and safe software. Just take a try!

It went good but then won't connect to 3G after that we called and they said something went wrong but nothing did so I'm wondering is there anything i could possibly do to fix it or should I call the place that did it? Or should I just call sprint or apple? Please help I have to use my phone a lot in places that don't have Wi-Fi.
