updated and now i have no service

[adamhsufc]

im not exactly a genius when it comes to iphones so i went along and updated it to the 5.1 software not knowing my jailbroken iphone would become unjailbroke. Before the phone was unlocked which now means it no longer reads my sim card, anyone have any idea of what to do? help would be greatly appreciated. thanks

What kind of phone is it? If it's an iPhone4, unfortunately there's nothing you can do since by updating your firmware you also updated the baseband to one which is not currently unlockable.

Just out of interest ( and sorry to the OP I really feel for you ) what would one do if you did this? Presumably you just have to get a SIM of the carrier you are locked to? If its not a 4S you can have a tethered jailbreak but it's losing the unlock thats the problem.

yeah a sim of its original carrier is your only option, unless you update to the ipad baseband which is unlockable but i wouldn't do this because its supposed to really mess with your phone, stop your gps from working and is irreversible! but its your only unlock option.

What model phone do you have? Do you know its original carrier?

Remember, though, the iPad BB is only applicable on the 3G.... and 3GS' made before week 35 of 2011.

Yeah, i was waiting for him to reply with his phone model

[Hungryghost]

Hes probably freaked out when he realised what he's done. :-)

[davegurn]

i would say lol but its so harsh to lose an unlock like that, and it happens to so many people.

I don't use an unlock but i knew about not updating my baseband because i did my due diligence, if everyone just read the forum and a couple of website for a few days these things would happen alot less often.

i'm not havin a go just now the OP is screwed when this could easily of been avoided.

[Hungryghost]

Yes sorry little inappropriate. Thanks for toning it down for me!

Hey

I just thought if your in the uk the original carrier that the phone is locked to ie O2 should be able to do an imei unlock on your phone aslong as its not stolen or anything like that and you dont even need to send them your phone as its done remotley, i think its a factory unlock as you can update your firmware as much as you want without losing your unlock.

I bought my 3gs second hand and contacted o2 and they said they can imei unlock it for £15 which i think is a bargain as at one stage websites were selling this type of unlock for as much as £100 but they got cut off! (if you have a contract with o2 they will even unlock your brand new phone for free but obviously your still bound to the contract), i imagane other uk carriers will offer the same service so contact whichever carrier the phone is originally locked to and ask them.

So if your in the uk and need it on another network thats probably the best option, i read on another thread that usa carriers won't do it but i might be miss informed.
