The same thing is happening to bluetooth, it finds other devices but don´t get connected, even wi-fi, sometimes it ask if I want to connect to a network, but don´t get connected, I think its only the antenna...

I have warranty but in Brazil they don´t want to replace my iphone, our consumer protection here is very weak

I'm suffering the same issue since 3 weeks ago, today I updated to 3.1.2 (Jailbreak) but it's not the solution.

I can almost guarantee it is an overheating issue, lots of people are suffering the same thing. Someone's at Apple discussion forum fixed it putting the iphone on the freezer, but its not a real fix. Apple has stolen us.

So???????

what about this problem?? Is possible to change the wifi antenna??

I'm not in warranty (out for 2 weeks), so the apple care told me that I can change (for the second time) my iphone with one refurbished, at the $@!&@@$ price of 210 euros...

I'm not so happy about the customer care of apple. they change me the iphone the 1st time with a refurbished one with the battery down... and now I need a new one because the battery life is about 5 hours and the wifi doesn't work.. I've to pay??? 90 days for the extended warranty is too less.

Well.. If somebody knows how to change the wifi antenna, just tell me something, in the meanwhile I'll change the battery. thx a lot. Tommy

As strange as this sounds.... I have found that if you go to settings and turn on Airplane mode and turn off Wi-Fi then go to /General/Network and turn off all of the settings: Enable3G/Data Roaming/Wifi ect. reboot your iPhone and turn Airplane settings back Off as well as turning your 3G and WI-FI back on to your original settings...I have seen the Wifi start working... It's more of a corrupt Preference Issue at times than a Hardware... it's a quickfix.. that can save you money...were all about saving money...

I've encountered a similar problem... My wifi does not seem to pick up any network. I'm thinking this is more of a hardware issue where the antenna has disconnect from the motherboard or is just broken. I'm not keen on opening up my iPhone so unless anyone has a different suggestion I think I'm going to take it to apple and eat the 199 fee.

I returned several iPhone 3g handsets, each time they were replaced (for refurbished) and each time the same thing happened, broken wifi. Turned out the cable on the charger was slightly frayed. It charged properly and transferred data for backups etc, but fried the wifi chips.

Apple had replaced handsets but left me with the original data cable and plug. I was pulling my hair out trying to figure out what was going wrong with the handsets. After ruling out software updates, magnetic fields etc, I bought a new charger/data cable.

Lo and behold - no problems!

If Apple store had given me a complete replacement first time (including cables and charger) it would have saved two subsequent handsets from fried wifi chips.

here is the solution:

Turn on your iphone and reboot with 3 second shut down setup as mentioned by apple. Press and hold the top button for 3 seconds and then press home key. Wait for apple logo to appear. Once completely shut down. Turn on itunes on your computer and sync your iphone. Make sure to backup your data first. Once your iphone is sync only tick off the ipod songs and camera roll option. Then restart your iphone and go to settings then general then reset and click on reset all network settings. Please note that if you have turn on passcode on your iphone you have to shut that before starting this step.

This will erase all your network cache. Reboot iphone one more time and this time make sure to keep pressing the home button for 3 seconds only when you see the apple logo appear. If your timing goes wrong here I am afraid you have to do the steps again. Its frustrating but thanks to apple for putting us through all this crap.

Hope this all helps.

Make sure to reach your office or school on time if you are trying this at night

Bingooooo wifi fixed :)

cheers

same issue here. it happens if u update your modem firmware from whatever it was to the latest version to date: 4.2.1. apple, of course, has a serious issue at hand but offers no fix to the problem. some may work wit these fixes but most dont. u can keep resetting and rebooting all you want and it still might not work and on top of that, if u dont do a back-up often, then your data will be lost.
