Hi Guys..
Need your help.. I have an Iphone 2G updated 1 month ago to the version to 3.0 The process went perfectly fine and functioning. Yesterday I removed personal data to sell the phone.....and now is locked swhowing only the Dev Team pineapple logo and nothing is functioning!! How do i unlock it ??
Have you tried holding power and home and get it to reboot?
Otherwise it sounds like your going to have to put the phone in DFU mode, restore and re-jailbreak.
