iPhone 4 Greyed Out Wifi

I have an iPhone 4 that I dropped partway in water. Due to the wetness, I turned it off ASAP and then threw it in a bag of rice. I waited a day and then powered it on again. It seemed to be partly working; I could sync to my PC and also could faintly make out the screen. For some reason, I decided to go ahead and update from iOS 5.0 to 5.0.1 while the phone was down. This went fine, although my screen was dark so I couldn't verify very much. I then took my phone apart and placed it in tupperware with rice. I waited another day and everything appears to be working, except for the wifi (greyed out) / bluetooth (can enter menu but it never finds it). I had read that some people have had issues with wifi after updating to 5.0.1, but I am also thinking it could be a hardware issue due to possible water damage or reassembly. On a side note, I have not jailbroken.

I was wondering if anyone here could provide me with some troubleshooting instructions. I have reset the network settings, hard restarted, and restored my iPhone to no avail. My wifi address is N/A, and my bluetooth has an address, but I can't turn it on. I have an IMEI and my modem firmware is 04.11.08.

Thanks,

Brett

A day simply is not long enought to allow the device to fully dry out. At this point, the device is essentially hosed. It's time for an Out of Warranty replacement.

Another bump hoping to catch someone's eye~

@diesel: My phone was dry enough to work. As a matter of fact, everything except the wifi/bluetooth is functional. I can make calls, check email over 3G, and do most of the vital functions of a phone (just not on wifi). I figured it would be fine because the flash LED was constantly on before putting it into the rice due to the moisture shorting out pins. After it dried, I recharged it and the LED was not on. As an electrical engineer, I understand the risks of moisture and how easily chips can blow. And as far as a replacement goes, I will be getting a 4S in March when my contract expires. I would like to use the phone for some home automation via wifi, so fixing it would be convenient.

If anyone has encountered a similar problem, any advice (such as issues that could arise from semi-careless reassembly) would be appreciated.

Thanks,

Brett
