Root 5830i ?

I phone 4 16GB with new screen
My Iphone 4 for sale. Has a cracked outer glass but I have a full replacement glass kit to swap it over. Phone still works fine even with the cracked glass so does not need a new LCD Digitiser. Kit is supplied with screwdriver set etc but I am not very technically minded so best to leave it to someone else. Priced it up in NCL city centre and was £35 but I rekon someone could do it cheaper.
