I have an iphone that I am trying to jailbreak to unlock, but there is a problem.
When I got the phone it was already jailbroken with 1.0.2 firmware, buy I noticed when I went to the edit URL section of the phone button at the bottom were not responding (cant add Symbols like colon or select .com, etc.). So I Upgarde it to 1.1.1
to jailbreak add unlock it but still having the same problem.

I further upgraded it to 1.1.2 then downgrade to 1.1.1 to jailbreak and unlock and still having the key problem; not responding.

NB: When I'm not at the edit url section of the phone that part of the phone works ok. But as soon as I go there no response. So I'm curtain its software problem, but dont know how to solve it.

Need your help team.
Thanks.
