My ipod touch 16gb 1st gen 2.2.1 jalibroken suddenly went crazy. i was playing games with my ipod touch and suddenly it restarted and my home button cant work anymore when i switch on my wifi it cant detect any wifi around. i tried reformating it but it still doesnt work but when i plug my cable in the home button will work 1/10 time. i dont think its a hardware problem cos if it is the home button cannot work at all but when i put the cable in it will work 1/10 time.but when i jalibreak it i hold the home button it works? any advise to be given?
