hi, i bought the new ipod touch 4g three days ago, and the second i got home i jailbroke it. then i went to the local mall, to buy a cover for it, and i noticed it kept turning off. i thought it wasw weird but only later oni understood it was turning itself off because it thought was of battery. now constantly i run out of baterry when i still have like 50-40% left. then i recharge it and after like 1 min it has 50%, and yesterday i left it charging all night and it didnt reach 100% only like 65 or 70%. THE WORST PART: i somehow did something i NEVER EVER EVER thought was possible: i lost the receipt, so no returning. Please , can someone help me? if needed im willing to buy a battery off ebay and change it.
