My iPhone now starts up (shows the apple logo and goes into reboot loop) ONLY when plugged into the wall charger and as soon as I take it off from the wall (or from the phone), it goes dead again (the battery is still about 40% after 5-6 hours of trying this. Can't get to switch it on with USB on my MAC. The only condition it will switch on is when plugged into wall charger. I jailbroke it a few days back through jailbreakme.com and installed 2 apps - SBSettings & lockinfo Can't take it to Apple as when it boots up, it shows the Lockinfo notification. I wonder if anything can be done as it is just not switching on or being detected by computer, so how will anything be modified in it. Any help would be highly appreciated.
