Hi everyone, I'm new on this forum, I'm normally active on other Apple forums but since I couldn't get answers there I thought I try here. I was using an iPhone 4, iOS 4.2.1 jailbroken Greenpoison up to about 2 months ago when I switched to the Samsung Galaxy S2 as it was free from my company. I thought I would keep the iPhone and give it to my sister or just sell it on ebay. Anyway I cleaned it and kept it in the original box in my drawer, and just a few minutes ago I realised there was still some info in the phone I needed. I have not reformatted the phone yet. However, although I charged my phone to 100% before keeping it, I could not turn on the phone. Connected it to the laptop, it stuck in a loop between a black screen and the Apple logo. Connected to mains charger, it started, battery life was indeed 100%, but then it was stuck on the lockscreen, with the 'slide to unlock' only giving me option for emergency call. Shows no service. Tried a hard reset, couldn't do so. Any ideas guys?
