Jailbreaking a iPhone 3G

[bristolrovers]

I bought an iPhone 3G the other day from some guy I know.

I was quite happy with the phone, it has his sim card in there. His number is showing up, and there is full signal and 3G Coverage. Whenever I try to make a call it says call failed, cant send texts. basically none of the phone works when it comes to sending texts/emails/internet/calls

I've come to the conclusion it is blocked. If I jailbreak it will that unblock it? I paid a fair ammount for it, And I know its wrong to unblock it IF it was stolen. But he's not only cheated the person he stole it from, but also me!

I heard jailbreaking would unblock it..

you need your own sim card

why would you expect his to work other than allowing you to activate the phone? There is no way you will just get free service

He said there was already a SIM card in the phone.

I'd expect it to atleast say "Welcome to the 02 pay as you go service, you do not have enough credit to make this call" But no, nothing. "Call back" It doesn't even ring... But I have full signal? hmm

delete!

Why would you delete it? I'm not even sure its blocked. It just sounds like it... If anyone else could confirm it.

I'm 99.99999% sure it's blocked. I know most cell phones still show signal and even the company name even when blocked. I don't know, but I'd assume iPhones are the same.

Jailbreaking won't "unblock" service usage. Jailbreaking simply gives you full read and write abilities to all the folders on the phone.

Sorry. Just try a differnet SIM

Sorry if you take my post wrong. The #s on the sim has been disconnect or cancel the service. So, the #s is available to use, you can activate it through your phone with your credit card info and you will get the service continue.
