Should I replace the bluetooth IC Chip?

I have an iphone 3gs with no wifi, no bluetooth, no imei, no baseband info. I've read online somewhere saying that it may be the bluetooth IC chip? If so how would I installed it myself? Parts costs about 80bucks on ebay. So im guessing, installing it by pulling old one out and place logic board with new ic chip in the oven and hope that they bond together?

have you just done a jailbreak? or got baseband 6.15.00?

no i wouldn't do the oven trick. you might desolder more than you solder and have more problems... I tried an oven reflow (twice on the same board) and nothing at all changed. if you don't have the skills or equipment then pay your local repairman!

Yea i just did an jailbreak with snowbreeze 2.2.1 for firmware 4.2.1. After that this happened. I'm not sure what baseband I got since I've let itunes restore iphone to latest updates before I decided to jailbreak. It's very possible itunes updated the iphone to 4.3 and that might've automatically given the iphone 6.15.00 baseband?

go to settings/general/about and see what the baseband is now. I am fairly sure you have just done the ipad 3.1.3 JB which is known to wipe out your wifi etc. They didn't warn us about that when they said you could jailbreak BB 5.13.4 or whatever it was that the iOS update for 4.2.1 gave you. THey are trying work out a patch for this as not all people who do the jb end up with the wifi problem. Be very careful about how you try to repair this as I ended in the recovery loop.... another problem of this jb!!

this is a software problem, not an ic problem. no soldering required. the wifi settings have been changed during the jb to those of an ipad.. restoring may solve the problem, but it will not change your baseband to what it was before unless your phone has bootloader version 5.8

what you will need to do is

a) download forecast from ireb's site- this will check your bootloader.

if you do have 5.8 then you can download fuzzyband from cydia and roll back to which ever baseband you had prior to the jailbreak

b) download the ios version you want...ie 4.1 from http://www.felixbruns.de/ipod/firmware

c) plug in to itunes and when chosing restore make sure you alt+restore and point at the new software (mac)

hopefully you'll have your phone back as it was before you decided to jailbreak!

if you are unfortunate enough to have bootloader 5.9 then you're stuck for a while.

you can try downgrading to 4.1. but it may not help

So, I've used forecast and the bootloader and baseband shows blank, jailbreakable? only with SHSH blobs. Actually I had to jb because the phone was in the connect to itunes screen or make emergency calls only. Do you think I can use snowbreeze 2.2.1 with ios 4.1 and shift+restore the phone?
