    Long story short, no SHSH blobs, no restoring to a new firmware and jailbreaking it untethered.

    Unless the phone was owned previously by a jailbreaker or a very wise person, I doubt that your device will have these blobs saved... so your only choices may be to either jailbreak the device at 4.3.3 or restore it to the current 7.0.3.
