Help with jailbreaking and Cydia for iPhones, iPads, and iPod touches.

evasi0n7 can jailbreak iOS 7.0-7.0.6 untethered. p0sixspwn can jailbreak iOS 6.1.3-6.1.5 untethered (see here for 6.1.6).
How to jailbreak iOS 7.0-7.0.6 (and fix problems). iOS 7.1.x is not jailbreakable, except an unsupported tethered iPhone 4 jailbreak.
Restoring or updating will update your device to iOS 7.1.1 and remove your jailbreak. There is no way to downgrade from iOS 7.1.x to 7.0.x.

It's possible to jailbreak it - just follow the instructions linked at the top of the page: How do I jailbreak iOS 5.0.1, 5.1, and 5.1.1? Jailbreaking it will also "hacktivate" it (unofficially activate it) so that it can be used as an iPod touch.

The concern with the serial number is really whether it's an "old baseband chip" or "new baseband chip" device - having an old/new bootrom is unrelated. It looks like that serial number is old enough to be compatible with the iPad baseband - see the carrier unlocking guide.

However, ultrasn0w is only compatible up to iOS 5.0.1. If you want to unlock it with ultrasn0w, you'll have to check to see if the device has SHSH blobs and then if it does, use them to downgrade the device - see here for a complete guide to this process.
