well, basically my iphone wifi is not working anymore, whenever i tired to turn it on, it wont detect any access point. eventually my iphone will hang, and ive gotto force reboot it.

also sometime, when my iphone could not detect my wifi mac address (grey wifi) then its getting frustrating, cos whenever i left my phone in sleep mode, incoming calls i wont get any alert.
all these problem is really killing me T___________T . tried fully restore a few times, but its not working...sigh...thts y i suspect its hardware issue
