    I have a iphone 3gs 32gig. It is in 3.1.2 and unlocked with blackra1n.

    I put my t-mobile sim card and friend's sim card and it dose work. but the signal is very weak, it only work outside and only have 1-2 bars of signal... Not working at home, no signal no service... Anyone know how to fix this problem? i have tried to reset the network setting and still the samething.

    Actually that's common, since being a simple phone is not a strong point of the iPhone, according to many. So, if you're barely getting any bars with a regular phone, I could see that happening. Try an area where you have full bars.
