Just got my new iphone with a 1.1.4 firmware version. I unlocked, jailbraked and activated it with Ziphone 3.0, and everything was OK. started to enter my contacts manually, and at some point(I don't recall very well the exact moment) I realized that when I pressed the buttons I have no more sound coming out from my phone speaker. I'm very nervous because is brand new, so I tried some stuff that I Googled: - the plug/unplug fast and slow out of the phone's jack - the reset all settings - clean the jack, even if the phone is new and no clog is there - restore to it's factory settings(a full restore) and unlock again I can still use it to make phone calls, I can talk and hear through my earphone, and everything is OK if I plug in the the headphone(buttons sounds and everything). But when I take out the headphones there is still no sound and I have to rely on my tiny vibrator to notify me when someone calls. Have I done something wrong in the unlock process? the Ziphone is one click do everything...so.... I tried listening very close to the phone's speaker and there is an attempt to play the sound(I hear the sound but very very low). so the speaker is still working but there is "not enough" signal to play since I hear a dimm sound. Is there some link between the firmware, unlock program, ITunes version?? should I try with a downgrade? or maybe a diferent unlocker or version of ziphone? I'm pretty worried that I even searched for new jack assembly for the iphone, and found at about 25$, but since is a new phone I don't know if this is a hardware issue. I've been reading there is the chance that the phone is trapped in headphone mode, but I can't seem to locate the sensor in the jack to see if there is something blocking it. If anyone knows some technical details on this please share. Is it just a contact that acts like a sensing sensor? Maybe if so there is a chance of a bad contact or something. It would help to have a jack schematic..... If anyone has any idea please let me know how to solve this issue.
