Hello all, I'm a noob in terms of unlocking (never unlocked any of my phones and I've only jailbroken one of my older iPhones once - and then undid it later). I'm planning a trip to Ireland soon and I created a new post about it here:

But I figured I'd reply here, too, since it might get more attention.
1) Do I need to jailbreak my phone before I can unlock it via swiftunlocks?
2) Will this unauthorized unlock cause me any trouble with my continued AT&T usage? What about if I have to bring the phone in to AT&T or Apple to deal with an issue?
3) Once unlocked, can I just find a SIM card somewhere after arriving in Ireland and save a lot more money by using that versus using something like AT&T's international roaming plans/add-ons?
4) Will I be able to use affordable data with one of the SIM cards/plans in Ireland?
4) I have an iPhone 5, but my wife and daughter have 4S's. Any issues with either of those models?
