Ok, I have searched the forums for this issue but I have found none. Sometimes, when connecting my iPhone 3g 16gb to my macbook pro, instead of charging the battery, it drains it. Not quickly or anything, but for example: it is 20% left, it charges 'till 70-80% it stays there, and then decreases until 20% again. I have to unplug the iPhone, restart it, and connect it again in order to charge. Now, this issue is random, and it didn't happen until I upgraded to 3.0 firmware. And yes, the iPhone it's jailbroken (pwnage tool), and no, it's not unlocked. Does anyone else have this issue? is this a common bug or something? Any recommendations on how to fix it (besides restoring the phone)? Extra info: this only happens when connecting it to a computer, using the power socket it seems to work ok. Thanks for the input, and sorry for the possible bad grammar and/or english.
