Hey, I had a few samsung INNOV8's some time ago... I unlocked 1 of them at a service shop and it suddenly started having battery problems like it would only last a maximum of 1 day... now i still have 1 more of this type of phone but I am worried to unlock it because it might give this same problem to me again, because when i went to another service shop the technitian told me that he had already unlocked 5 of those phones and they all gave the same problem so he advised me not to go ahead with the unlock... this was about 4 or 5 mnths ago and i was hoping that something might have come out that doesn't give this problem... any information or suggestions plz?
