I'm studying abroad in London next semester, and I'd like to use my iPhone 4 while I'm there. I need some help figuring out how to jailbreak and unlock my phone, and what UK plan to use when I get there.
I've had an iPhone since 2007, but I've never jailbroken my phone or had any urge to do so. All I want is to replicate the experience I have with my phone now, just in England. I'm completely happy with my phone in its current virginal state, and I have zero desire to install a bunch of crazy apps or change its appearance or whatever. I just want to use it on a UK network, keep all of my current apps, and restore it when I'm back in the US.
I've seen this question
, but that person has a 3G and it seems like the jailbreaking situation for each model, firmware version and baseband version (???) is different, so I need some help navigating the various options.
My iPhone has firmware 4.1 and baseband version 2.10.04, which leads me here
on the site linked in the previous question. There are like four different jailbreaking options on that page, though, and I can't figure out which one will definitely let me unlock. I also don't know the best way to unlock my phone once it's jailbroken.
As for the plan when I'm in the UK, I've found 3's iPhone 4 SIM-only plans
, which seem like they offer what I want. I've never used a pay-as-you-go system before, though, so I could use some help figuring out how they work and what the potential pitfalls are. I'm not a huge data user or texter, but I definitely want both capabilities when I'm abroad. I've used, on average, less than 50 MBs of mobile data a month across the lifetime of my phone, so I'd rather not pay for a GB of data a month.
So, tl;dr: I need basic, step-by-step instructions for unlocking my iPhone 4 with the least disruption possible to my current setup. I also need some advice on getting a pay-as-you-go plan working on my iPhone in the UK.
